i have an html file like this. from where i want to retrieve the company name, share price and other values. there isn't any id or name attribute to retrieve this information easily. can you suggest me how to do this?
N.B. i want to use javascript/ jquery / php framework.
In general, seeing you dont say anything about a language or a more specific situation, you can use XPath to select the values you want.

In an ASP.Net Core web app, I'm passing a List<Parameter> to a view via ViewBag.Parameters. The view also has a SelectParameterViewModel that consists of one property only, an int ParameterId. The objects are then displayed in a table like so (I skipped straight to tbody as the view works fine from a cosmetic perspective):
#model WebApp.Models.ReportViewModels.SelectParameterViewModel
[...]
<tbody>
#foreach (var item in ViewBag.Parameters)
{
<tr>
<td class="col-xs-1">
<form asp-controller="Report" asp-action="Launch">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<input asp-for="#Model.ParameterId" type="hidden" value="#item.Id" />
<input type="submit" class="btn btn-primary btn-sm" value="Select" />
</form>
</td>
<td class="col-xs-8">#item.Description</td>
<td class="col-xs-3">
<a asp-action="Edit" asp-route-id="#item.Id">Edit</a> |
<a asp-action="Details" asp-route-id="#item.Id">Details</a> |
<a asp-action="Delete" asp-route-id="#item.Id">Delete</a>
</td>
</tr>
}

I would like the user to click on the button of the chosen table-row and submit either that row's Parameter (preferred) or the Parameter's Id, like I tried to do in this case. I would then do the same with the <a> tags on the third column. The point is that I don't want the user to simply type /Report/Launch/id and run the report, as each user would have its own sets of parameters and should not be allowed to use any of the others', and the ViewBag only contains the list of its Parameter. I can change the view model and/or the receiving controller's argument depending on the solution, both would work. I tried a few versions of the above html, but none would work, while the above returns ParameterId with value 0.
I couldn't find a similar scenario in other SO questions. There were some solutions that involved JavaScript and, correct me if I'm wrong, but that would still show the ParameterId value in the webpage source. While that would be sort-of-ok in this specific case, I have other cases where I definitely would not want that to happen.
What would be an elegant solution to achieve this? Thank you!
I am new to Grails and I am trying to get a template navigation bar to be populated dynamically through a controller. I am really close to solving this but seem to have run into a wall lately.
I currently am getting the navigation to populate only when I click on the link for that controller. Every where else the navigation just populates the bullet points for the links. I am probably not referencing the controller correctly in my template but have not found any good examples yet.
using Grails 2.3.3
the controllers are dynamic.
Here is the code for my navigation template
<body>
<!-- Links to the committees go here -->
<div class="leftMenu">
<!-- template of hospitals and there committees goes here -->
<div>
<g:render template="/hospital/committeeTemp" />
</div>
<tr valign="top">
<td>
<a href="index.jsp?nav=main&hosp=<%=hospGiven %>" target="_top">
<img src="/Trustees/static/images/img/navigate.events.gif" border="0">
</a>
</td>
</tr>
<tr valign="top">
<td>
<a href="index.jsp?nav=main&hosp=<%=hospGiven %>" target="_top">
<img src="/Trustees/static/images/img/navigate.news.gif" border="0">
</a>
</td>
</tr>
<tr valign="top">
<td>
<a href="index.jsp?nav=main&hosp=<%=hospGiven %>" target="_top">
<img src="/Trustees/static/images/img/navigate.help.gif" border="0">
</a>
</td>
</tr>
<%-- </table>--%>
</div>
</body>
I am using a nested loop to populate the navigation bar. That code can be found here Grails navigation links nested loop
With a little more knowledge under my belt. I found out that it was only populating on that one page because that is where it was accessing that particular controller's action. So I ended up putting that mapping into ever action in my controller.
Hi I have the following code in my grails gsp
<form action="upload-script-url" method="post" enctype="multipart/form-data">
<table class="table"style="width: 75%">
<tr>
<td>
<span style="font-weight: bold; ">Select the Source File:</span>
<input size="75" type="file" id="payload" name="payload"/>
</td>
</tr>
<tr>
<td>
<input type="submit" class="red" id="Run">Run</button>
</td>
</tr>
</table>
</form>
I read the form parameters from: here
Are those right parameters in the html form?
Now how should I proceed to read the data from the selected file? do I have to use the apache commons fileupload api ?
Thanks
request.getFile("payload")
and you will get a CommonsMultipartFile
If you take some time to (again) actually look at the documentation you will see how to do it...
i am having the same problem as in this thread
jQuery unexpected sortable behaviour
my system is doing identically the same thing. the only difference between my code and his code is that my code is 100% generated by ajax on the fly, and im inserting tables into each of the LI, but alas the results are the same. here is the html im inserting for each of my master list entries.
here is the blank list thats in my html
<ul id=\"questionList\">
</ul>
this is generated by javascript and ajax calls on the fly
<li id="liName-11" class="ui-state-default">
<table width="600" border=".5" cellspacing="2" cellpadding="2" class="singleBorder">
<tr>
<td width="386" align="left" valign="top">

folling the suggestion in the above thread, ive modified his suggestion into this
$("ul.list").live("mousedown", function(e){
e.stopPropagation();
});
but it has zero effect. works perfectly in chrome and firefox, but screws up in IE. trust me im about to just put in a script where if they see the site in IE that it will forward them to firefox and tell them to download a real browser but my boss doesn't like that idea. you guys have any idea?
Make sure your html is valid: you are closing your <span> elements with </edit>
Your script applies to a ul element with a list class which you don't define anywhere in your html.
http://api.jquery.com/event.stopPropagation/
You'll notice on this page that live() handles an event after it's already propagated up to the top of the document, so you'll need to use bind() instead of live().
I'm a Grails noob and running into something that seems to be a bug, but it is entirely possible I'm not configuring everything correctly.
I've got two simple Domain Classes:
class Player {
String firstName
String lastName
static constraints = {
firstName(blank:false)
lastName(blank:false)
}
String toString() { lastName + ", " + firstName }
}
and
class Team {
String mascot;
static hasMany = [players:Player]
static constraints = {
mascot(blank:false)
}
}
I have controllers for both that do nothing beyond dynamic scaffold these two Domain Classes.
But even when I have a list of Players in my DB, I don't get a multi-select box for them when creating a new Team.
However, the multi-select shows up when I go to edit a Team
Is this a bug in the dynamic scaffolding for new items, do I misunderstand how this is supposed to work, or is there something else I need to declare here?
Any help is hugely appreciated! I've got screenshots that StackOverflow won't let me add because of my newness, but I'd be happy to show them another way if that'll help.
I finally figured this out and wanted to pass on what I did just in case someone else runs into it.
When I generated the views for Team, the form block in edit.gsp looks like this:
<input type="hidden" name="id" value="${teamInstance?.id}" />
<input type="hidden" name="version" value="${teamInstance?.version}" />
<div class="dialog">
<table>
<tbody>
<tr class="prop">
<td valign="top" class="name">
<label for="mascot">Mascot:</label>
</td>
<td valign="top" class="value ${hasErrors(bean:teamInstance,field:'mascot','errors')}">
<input type="text" id="mascot" name="mascot" value="${fieldValue(bean:teamInstance,field:'mascot')}"/>
</td>
</tr>
<tr class="prop">
<td valign="top" class="name">
<label for="players">Players:</label>
</td>
<td valign="top" class="value ${hasErrors(bean:teamInstance,field:'players','errors')}">
<g:select name="players"
from="${Player.list()}"
size="5" multiple="yes" optionKey="id"
value="${teamInstance?.players}" />
</td>
</tr>
</tbody>
</table>
</div>
<div class="buttons">
<span class="button"><g:actionSubmit class="save" value="Update" /></span>
<span class="button"><g:actionSubmit class="delete" onclick="return confirm('Are you sure?');" value="Delete" /></span>
</div>
</g:form>
but the form block in create.gsp looks like this:
<g:form action="save" method="post" >
<div class="dialog">
<table>
<tbody>
<tr class="prop">
<td valign="top" class="name">
<label for="mascot">Mascot:</label>
</td>
<td valign="top" class="value ${hasErrors(bean:teamInstance,field:'mascot','errors')}">
<input type="text" id="mascot" name="mascot" value="${fieldValue(bean:teamInstance,field:'mascot')}"/>
</td>
</tr>
</tbody>
</table>
</div>
<div class="buttons">
<span class="button"><input class="save" type="submit" value="Create" /></span>
</div>
</g:form>
In other words, for this corner case, the default Create view omits the widget to properly display the multi-select list. When I did a copy and paste of the missing code, the dynamically scaffolded controller picked it up and persisted it as expected. So, it's definitely a bug in the view generation code.
Yes, the default scaffolding puts a parent selector in the child class' create/edit page.
I'm guessing it was just easier for them this way. It shouldn't be a multi-select though, just a pull-down single-select, as it's a One-to-Many.
As you've explained you wanted more of a Many-to-Many relationship, you might try adding:
static hasMany = [teams:Team]
to your Player class. I've found that Grails does better with bi-directional relationships. It's also useful to have when building search queries, and shouldn't require more than the one relationship table you'd already need.
If you're using Grails pre-v1.1, Many-to-Many relationships aren't directly supported, so even adding the static hasMany above won't be the complete solution, as you'll need to manage adding to the other list when you add to one direction. I haven't used v1.1 yet, so I can't talk about what is needed to specify the Many-to-Many in it.
I encountered the same problem using current version (v1.3.4) of Grails. Had to manually modify the create.gsp
