How can I pass html object properties into embedded ruby code in an html.erb file?
Lets say I have a ruby method A that accepts a string parameter(and also the return value of A is string). I think of scenarios like the following:
<input type="text" id="t" value="Leaves">
<%= A(document.getElementById("t").value) %>
Obviously I can't write code that way.
I want to pass the value/text of the textbox into method A and print A's return value into the html body. How can I do that?
Also, if I want to continuously check the value of the textbox and append A's return value(when passed the current value of the textbox to A) to the body of the document, what should I do? And if I instead wanted to set some paragraph p's text to this return value, what should I have done?
You can use a HTML parser like Nokogiri.
frag = Nokogiri::HTML.fragment('<input type="text" id="t" value="Leaves">')
frag.at_css('#t').attr('value')
But it seems like a rather silly and overcomplicated solution to something that most likely can be solved by not using HTML strings to pass around data in your views / helpers in the first place.
For example this HTML
<div>
<span></span> I want to find this <b>this works ok</b>.
</div>
I want to find a DIV with I want to find this in it and then grab the whole text inside that DIV including child elements
My XPATH, //*[contains(text(), 'I want to find this')] does not work at all.
If I do this //*[contains(text(), 'this works')] it works but I want to find any DIV based on I want to find this text
However, if I remove the <span></span> from that HTML, it works, why is that?
text() only gets the text before the first inner element. You can replace it with . to use the current node to search.
//div[contains(., 'I want to find this')]
This will search in a string concatenation of all text nodes inside the current node.
To grab all text you can use node.itertext() to iterate all inner texts if you are using lxml:
from lxml import etree
html = """
<div>
<span></span> I want to find this <b>this works ok</b>.
</div>
"""
root = etree.fromstring(html, etree.HTMLParser())
for div in root.xpath('//div[contains(., "I want to find this")]'):
print(''.join([x for x in div.itertext()]))
# => I want to find this this works ok.
Try using //*[text()=' I want to find this '] , this will select the div tag and then for text you can use the getText() method to get the text
You can try Replace text() with string():
//div[contains(string(), " I want to find this")]
Or, you can check that span's following text sibling contains the text:
//div[contains(span/following-sibling::text(), " I want to find this")]
I'm trying to render a Block's Field as Plain Text as I need it used as part of HTML, I've tried using |RAW however I read it was unstable + it didn't work haha!
This is my existing HTML minified

However I would like to make it more useable

This would mean that when a user modifies the DrupalBlock HEX code it would change the color of the box. However the issues is when it's printed on the page it's looking like this
<div data-quickedit-field-id="#" class="field field--name-field-color field--type-string field--label-hidden field--item quickedit-field">FFFFFF</div>
the only thing I would like printed is "FFFFFF" with no div's
-
Here is my question: How do I display my Field_color as plain text when it prints?
You can use |raw : {{ content.field_color|raw }}.
If you need more information please ask.
I suggest you do a dump or kint of your content.field_color variable. You might be able to get some more information on it and get the answer!
Anyway, we have something similar in our project and the way we do it is by using a .getString() method.
{% set image_align = content.field_image_align['#items'][0].getString() %}
<div class="{{ image_align }}">
Our field is a list of values so you'll have to look for another array item to call the .getString() method on.
In the following html code, One of the div is hidden and the other one is not.My question is
1.how to select any element with multiple class names with hidden attribute
2.how to get the inner html when the html is hidden or shown
I tried,
$('.middle-cont,.float-lft,.content-height').html()
$('.middle-cont,.float-lft,.content-height:hidden').html() //will this work
html
<div class="middle-cont float-lft content-height">
some html
</div>
<div class="middle-cont float-lft content-height" > //This div is hidden
some html123
</div>
no comma's, commas will select all elements with either of the classes, while removing the comma's will select the elements that has all the classes :
$('.middle-cont.float-lft.content-height').html()
wether or not it's hidden makes no difference for this.
FIDDLE
you don't need , to select element with multiple class....use html() to get the content.. (it doesn't matter if it is hidden or not)
$('.middle-cont.float-lft.content-height').html()
Comma using as OR operator, you dont need it here so:
$('.middle-cont.float-lft.content-height').html()
It's not matter that your element is hidden or not.
Try like this
var innerHtml = $(".middle-cont").filter(".float-lft").filter(".content-height").html();
alert(innerHtml);

HI All,
I know this is bit strange question, but please suggest.
I want to create a link on website url content in input type"text" field not any other html tag,Is it possible and if yes how.
Regards & Thanks
Amit
I don't know whether I understood your question correctly or not. Based on my understanding I gave the answer. Feel free to raise your question. Nothing is impossible.
</input>
It displays a text box. You can enter any data into it. If you press enter key then it forwards the page to Google.com
You can use SPAN instead of INPUT. This also serve the same purpose.
<a href="http://www.google.com" ><span style="border:1px solid blue;" >Link</span></a>
This is unfortunately not possible in the way you've asked it in HTML 4 or below. Even with HTML5 which has several new INPUT TYPEs, including URL, it only does validation and has some other useful functions, but won't give you want you want.
You might look for some jQuery plugins that can help you do this, most use the same principals behind Rich Text or other online/web-based HTML WYSIWYG editors. I've had trouble locating them myself.
These 3 situations (that I can think of right now) are pretty much what you will face natively with HTML4 or below, as text in an actual HTML4 INPUT textbox is pure text. It is not html and therefore NOT clickable. Here are some variations:
The INPUT tag's VALUE attribute, also referenced as the corresponding DOM object's "value" property (which is basically what you've been doing, and the most you can hope for, if you decide that you MUST have the text that's ACTUALLY inside the textbox (because the text inside the textbox is the VALUE attribute, as I have it with "http://yahoo.com" in this example):
<input id="myTxtbox" type="text" value="http://yahoo.com">
where the INPUT's VALUE = "http://yahoo.com", which you can retrieve with:
in pure javascript:
document.getElementById("myTxtbox").value
in jQuery:
$("myTxtBox").val()
When your link/url is the text in between the and , i.e. the text/innerText of the textbox. This is useless for your question/scenario since it's not clickable, and more importantly NOT INSIDE the textbox. However, someone might want to use this to retrieve any text that you may be using as a label (if you're not using the <label> tag itself already that is):
<input id="myTxtbox" type="text">
http://yahoo.com
</input>
The textbox's text/innerText is NOT an attribute here, only a DOM object property, but can still be retrieved:
pure javascript:
document.getElementById("myTxtbox").innerText
jQuery:
$("myTxtBox").text() -- you would use this to capure any text that you may be using as a label (if you're not using the tag).
The result being: http://yahoo.com
When your link/url is the form of an ANCHOR () with an HREF to your url (and visible link text) in between the and , i.e. the innerHTML of the textbox. This is getting a bit closer to what you want, as the link will appear as, and function as an actual link. However, it will NOT be inside of the textbox. It will be along side it as in example #2. Again, as stated in example #1, you CANNOT have actual working HTML, and therefore a working 'link' inside of a textbox:
<input id="myTxtbox" type="text">
<a href="http://yahoo.com">
http://yahoo.com
</a>
</input>
Once again, similarly to example #2, the textbox's innerHTML is NOT an attribute here, only a DOM object property, but can still be retrieved:
pure javascript:
document.getElementById("myTxtbox").innerHTML
jQuery:
$("myTxtBox").html()
The result being: http://yahoo.com
You could simply do this :
<input type=text value="link" readonly>
So whenever somebody clicks the textbox, it works as a link, and since it's read only, there wont be any text input/change.
Be careful tho, for it wont look like a regular link and might cause confusion, or may be misinterpreted as a normal textbox.
This is how I did it with JavaScript and JQuery. This wraps the entire text field in a hyperlink, so essentially the entire text field is click-able, which may not be the functionality you are looking for. It worked for my purposes though.
The reason I didn't just use a $(nameTextField).click(function(){...}) structure is because the text field I'm using has the disabled attribute set, so click functions aren't fired. That's why I had to wrap the text field in a hyperlink.
// Make person name a hyperlink to page in new tab
var nameLink = "/exampleUrl/?initStudentId=$" + studentId;
$("#studentNameLink").replaceWith($("#studentNameLink").html()); // Unwrap any previously wrapped text fields
$(nameTextField).wrap("<a id='studentNameLink' target='_blank' href='" + nameLink + "'>"); // Wrap text field in anchor
$(nameTextField).css('color', '#326699'); // Make text blue
$(nameTextField).val(studentName); // Set text field value
Half the people here missunderstood it. The OP would like to have the content/value of the input fields to be hyperlinks instantly and NOT the fields themselves.
It is doable... although it's not an input field but the appearance acts like such one.
Use the following: contenteditable=true
HTML
<div contenteditable=true>
<a id=lnk style=-moz-appearance:textfield href=http://www.google.com>http://www.google.com</a>
</div>
or optionally -webkit-appearance ..depends
JavaScript
var lnk=document.getElementById('lnk');
lnk.addEventListener('click',()=>{
window.location.href = lnk.getAttribute('href');
});

You want someone clicking a textbox to actually be treated as a link click?
Sounds malicious to me but you could bind the focus event via javascript to a window.redirect().
I don't know if I get the question right. As I've understood you want to be able to type in a ...-tag into an input-field. No other tags should be allowed. You can achieve this by using PHP for example:
<!-- HTML-Code -->
<input type="text" name="link" />
// PHP-Code
$link = strip_tags($_POST['link'], 'a'); // Remove all other tags than the <a>-Tag...
Is that what you mean?
Yes, it is possible, but it's not that simple. You need to create div, or other tag you prefer, that will be always floating over your input, using CSS positions, and create anchor inside it.
For example, virtual keyboard img is embedded into input field that way on russian Google page (http://www.google.ru/)
Because of browser-compatibility it's not a simple task.
EDIT: Understood your question a little more. You still need first part of the answer, and you will need to handle keypress event inside your input. When symbol is entered you will need to update your floating div.
So now task is difficult even more. Maybe you should revise your model and not the code.
