In JQuery Mobile, I have a navigation bar like the following:
<div id="nav_bar" data-role="navbar">
<ul>
<li><a>video</a></li>
<li><a>music</a></li>
<li><a>picture</a></li>
</ul>
</div>
Say now I want the nav bar to display "some content" only. This is my code:
$("#nav_bar ul").html("<li><a>some content</a></li>");
But the built-in JQuery Mobile style is not applied to it. How can I do this?
Thanks in advance.
When a page is opened, a script runs to add all the necessary classes. Replacing an item does not rerun the script.
I don't think you can do this without adding in the class manually by either specifying the classes in the text/using a variable or the following:
$("#nav_bar ul").html('<li><a>some content</a></li>').children('li').addClass('class-one class-two');
$("#nav_bar ul").html("<li><a>some content</a></li>");
.html() method destroys ul element and its contents then adds new content.
You should use .append() instead.
$("#nav_bar ul").append("<li><a>some content</a></li>");
If you actually want to replace the original content.
Target the div and use .html() method
$("#nav_bar").html("<ul><li><a>some content</a></li></ul>");

I'm using jQuery mobile 1.3.0 and trying to style dynamic elements of a listview. I have a list defined in a pages markup and can add elements to it from an object.
<div data-role="content">
<ul data-role="listview" id="list_logs">
</ul>
</div>
This is then the code to read items from an object and build the list:
for(log in data.logs) {
$('<li><h2>'+data.logs[log].date+'</h2><p>'+data.logs[log].event+'</p><p>'+data.logs[log].type+'</p></li>').appendTo('#list_logs').trigger("refresh");
}
From what I can understand from the documentation calling trigger("refresh") should style the list content but neither it or trigger("create") are doing much at all. Does anyone have any further insight into this? Thanks in advance.
EDIT: I should add that the stylesheets are in place in the document head and that adding elements statically results in correct styling.
Every component has a designed function for markup enhancement, listview uses:
$('#listviewID').listview('refresh');
In case this is fully dynamically create listview, not just li elements then this line should be used:
$('#listviewID').listview().listview('refresh');
Full list and examples can be found in my other ARTICLE, to be transparent it is my blog. Or it can be found HERE.
A question similar to this has been posted several time, but I cannot find a solution that works. Hopefully, someone can help!
I am using jQuery Mobile 1.1 and jQuery 1.7.2, so I'm on the most recent stable releases. I want to create a dynamic page header. Using this HTML code, it works fine:
<div data-role="page" id="levela">
<div data-role="header" id="hdr_levela">
<h1>Title</h1>
</div>
</div>
So I then go to dynamically create the title. I change the HTML to this:
<div data-role="page" id="levela">
<div data-role="header" id="hdr_levela">
</div>
</div>
And added the following jQuery code:
// Set the header
var dirHeader = $('#hdr_levela');
dirHeader.append('<h1>' + title+ '</h1>');
The title appears, but is not styled. I have found several posts about this. In the jQuery Mobile Documentation, it says:
"However, if you generate new markup client-side or load in content via Ajax and inject it into a page, you can trigger the create event to handle the auto-initialization for all the plugins contained within the new markup. This can be triggered on any element (even the page div itself), saving you the task of manually initializing each plugin (listview button, select, etc.).
For example, if a block of HTML markup (say a login form) was loaded in through Ajax, trigger the create event to automatically transform all the widgets it contains (inputs and buttons in this case) into the enhanced versions. The code for this scenario would be:
$( ...new markup that contains widgets... ).appendTo( ".ui-page" ).trigger( "create" );
So I tried several things. After the above code, I added the following:
dirHeader.trigger("create");
This had no effect. So I tried to put it on the actual append itself:
dirHeader.append('<h1>' + folderName + '</h1>').trigger("create");
This had no effect. I then tried the process on the parent element (in this case, the id of the parent div is "levela"). So I tried this:
$('#levela').trigger("create");
This also had no effect. At this point, I am completely lost. Every solution involves doing one of the things I have tried and is just not working. I must be missing something incredibly basic but I just can't seem to find it.
Thanks in advance for your help!
You can update the content by calling .page:
See this working Fiddle Example!
// Set the header
var title = 'super hyper BuBu',
$dirHeader = $('#hdr_levela');
$dirHeader.append('<h1>' + title+ '</h1>').page();
I just solved a similar problem -- it appears that jQM headers and footers do not have the "create" method, so as far as I can tell, the css classes and roles need to be added manually.
For reference, I posted an example fix on this (old) question: JQuery Mobile trigger('create') command not working
(Follows on from Can you define tooltips in Dojo wijit template?)
I'd like to be able to popup some help text if a user hovers or keeps the focus on a Dojo wijit for some time. I know that these wijits come with some prompt behaviours such as when they are empty or on validation errors, but I'd like to be able to prompt regardless of the content of the control. For example:
<input name="tooltipTesting"
data-dojo-attach-point="tooltipMe"
data-dojo-type="dijit.form.ValidationTextBox"
data-dojo-props="placeHolder:'Type Something',
required:true,
value: '${blah}'" />
<div data-dojo-type="dijit.Tooltip" data-dojo-props="connectId:'tooltipMe'">
Got to love hovering over links. Sometimes you a get a free tooltip.
</div>
Programmatic definition of the tooltips works for plain HTML elements like anchors, but nothing I do appears to associate a tooltip with other Dojo controls. Advice?
You can programatically connect the widget to the tooltip using
tooltip.addTarget(widget.domNode);
dijit.Tooltip connects to the DOM node(s), not to Dijit Widgets (i.e. javascript objects), but you can always use widget's reference to its root DOM node accessible via widget.domNode.
There is also a problem with your markup: dojo-dojo-attach-point does not assign an id to the widget (you reference from the Tooltip via connectedId). Define id property <input id="tooltipMe"> to do so, then the ValidationTextBox itself and also the root DOM node of the ValidationTextBox will have the same id. Note that you cannot use hardcoded IDs in the widget templates.
I've been trying to get a Dojo (1.6) dijit.Tooltip to work when defined in a wijit template.
So, if I have wijit template that includes the following:
<a data-dojo-attach-point="tooltipMe" href="" onclick="return false;">
Show a Tooltip
</a>
<div data-dojo-type="dijit.Tooltip" data-dojo-props="connectId:'tooltipMe'">
Got to love hovering over links. Sometimes you a get a free tooltip
</div>
I can see the link of course, but nothing happens when I hover. Scouting round the newsgroups it seems there might be a problem with defining tooltips in wijit templates, but it's not mentioned in the Dojo docs.
Is it possible to define tooltips inline like this? Or am I just doing something wrong, it seems like the obvious place to do it.
If not, is there an accepted approach for creating and linking tooltips to DOM nodes defined in wijit templates?
Tooltips connectId property has to be the id of a DOM node. data-dojo-attach-point is not an id, it just creates a reference in the instantiated widget.
So in your case you need to assign an id to the a-node and use the same id in connectId. To avoid id clashes when creating multiple instances of your widget you can use the ${id} variable substitution to ensure that all ids are unique:
Your code should look something like this:
<a id="${id}_link" data-dojo-attach-point="tooltipMe" href="" onclick="return false;">
Show a Tooltip
</a>
<div data-dojo-type="dijit.Tooltip" data-dojo-props="connectId:'${id}_link'">
Got to love hovering over links. Sometimes you a get a free tooltip
</div>
I've had problems doing it this way before. I used script to create them on my page after I had done some other work, maybe something like this will help you out if you use it in the template postCreate method.
var span = dojo.query('.hasEntry span').forEach(function(node, index, nodelist)
{
new dijit.Tooltip({
connectId:node,
position:"above",
label: toolTipLabel
});
});
Responding to an old thread here, but just wanted to share a solution for people looking to use tooltips without IDs on their custom widget elements. It's not as pretty as just using tooltip, but it works. It uses the "dijit/popup" and "dijit/TooltipDialog" modules.
this.editTooltipDialog = new TooltipDialog({
content: "<p>I love tooltips</p>",
onMouseLeave: function(){
popup.close(this.editTooltipDialog);
}
});
on(this.targetDiv, 'mouseover', lang.hitch(this, function(){
popup.open({
popup: this.editTooltipDialog,
around: this.targetDiv
});
}));
I tried to replicate the issue in jsFiddle: http://jsfiddle.net/phusick/EcLLb/.
I found out that dijit.Tooltip widget from the template is instantized, but it does not connect mouse events, presumably because DOM node it attempts to connect to does not exist yet (i.e. has not been added to document DOM tree).
To prove the aforementioned I tried to connect the tooltip in widget's postCreate method, when all DOM building is done and it worked:
postCreate: function() {
this.inherited(arguments);
this.tooltip1.set("connectId", this.tooltipMe); // w/o this the tooltip won't show
}
So you can instantize tooltips via a template markup and then just connect then to DOM nodes in postCreate method.
I use the jQuery-ui tabs widget as a navigation. Contents of all tabs are load via ajax. Seems that there is interference between tabs. I mean, for example, if in page1 in tab1, there is an element whose ID is foo, and in page2 in tab2, there is an element with the same ID. And in both page, there is javascript code to manipulate the element with ID foo, then weird things will happen.
How to deal with this situation?
You deal with it by having unique IDs - that is, after all the point of IDs. :) As far as jQuery selectors are concerned, yes, you can clarify which of the elements you mean as Bayard Randel explains, but it's a dangerous practice in general. I've found from personal experience that it comes back to bite you in the end - somewhere, somehow, you'll forget that you've got duplicate IDs. Just avoid them.
Seeing as you are using jquery, you can target the correct element by using selectors based on your tab name.
e.g. if you markup looks like this:
<div id="tabs">
<div id="tabs-1">
blah
</div>
<div id="tabs-2">
blah
</div>
</div>
you can specifically select the second link with this selector, despite the id duplication:
$("#tabs-2 #linkId").whatever();
