I'm using the jQuery Datatables plugin and I would like to customize some of the generated HTML for the filter.
Specifically, they generate the following HTML:
<div class="dataTables_filter" id="example_filter">
<label>Search: <input type="text" aria-controls="example"></label>
However, I would like my HTML to be more like this:
<div class="filter-search">
<label class="search-label">
<input type="text" placeholder="Search by name" />
<span class="search-icon"></span>
</label>
I've looked around and all I could find was something about changing the class, but in this case I want to change more than just the class.
I'm sure I can hack at the DOM after the table loads, but I was hoping there would be some way to do this as part of the config/initialization of the Datatable.
You can by modifying datatables oLanguage sSearch option:
$('#example').dataTable({
oLanguage: {
sSearch: '<i>Other Search Text</i>'
}
});
Without messing with the DOM after table load, I don't think there is a way to "change" the markup datatables generates for the filter without hacking the datatables plugin itself.
However, one decent alternative would be to simply implement your own search filter.
To make a custom filter OUTSIDE the datatables markup:
Step 1:
Omit the 'f' portion of the sDom parameter: https://datatables.net/usage/options
Step 2:
Write your own markup for a search field
Step 3:
Use something similar to the accepted answer for this question to actually filter on your own custom search field: Datatables - Search Box outside datatable
Otherwise, you're left with just making custom css rules for the markup generated by 'f' and/or moving it around.

I'm trying to get my head round templating engines and if there is something suitable for my requirements.
I'd like to specify HTML and provide dynamic functionality from within the HTML itself. For example, say I had a check box on a page
<label><input type="checkbox" id="cbox1" value="first_checkbox"> This is my checkbox</label>
I'd like to specify logic within HTML so that I display more content only if that checkbox has been checked, e.g.
// if #cbox1.checked == true
<h1>The check box is checked</h1>
// else
<h1>The check box is not checked</h1>
// end
Now, it is likely that liquid will be used to provide dynamic functionality based on a data store. So it'd also be nice to use the same liquid syntax to make the form dynamic (i.e. use liquid syntax in the if conditional above).
Is it possible to write a 'js engine', perhaps using jquery, that I could include in my web pages that would allow me to use liquid syntax but bind to variables in the 'js engine' as well as the data store to make my content dynamic?
Or, is there a better approach?
I would recommend using Vue.js (https://vuejs.org/).
The template engine is very easy to learn, and provides all the functionality you mention.
Here is a working example of your scenario:
https://jsbin.com/kikaxecogo/edit?html,output
But all you need to do is initialise Vue:
new Vue({
el: '#app',
data: {
showData: false
}
});
and write the template data:
<input type="checkbox" v-model="showData">
<div v-if="showData">
This is visible using v-if
</div>
<div v-else>
The check box is not checked
</div>
I've written a introduction guide to Vue.js here https://steveedson.co.uk/vuejs-intro/
You can also bind to other text inputs, data from ajax sources etc:
<input type="text" v-model="name">
<p>Hello {{ name }}</p>
And everything will update automatically.
As an alternative to Vue.js, there is also:

We have to be ADA compliant on our site. One of the things they look for is every form must have a label tag. The code has a label tag in the right place, but then when the javascript loads on the page, a span tag gets between the tag and the search field making it no longer compliant. I don't see a way to add a label. I was curious if anyone else had a suggestion for this or is there an alternative to typeahead that will work? In order to be compliant it must look like
<label for="search">Search: </label>
<input type="text" name="search" id="search"/>
For example the way it works now looks like...
<label for="search">Search: </label>
<span class="twitter-typeahead">
<input type="text" name="search" id="search"/>
</span>
There is no option to change the span tag that wraps your input. You can see where it is hardcoded in the source code here. Unfortunately, typeahead is no longer maintained either, so there will not be a future option to customize this.
However, you can always modify the code yourself. Either in the www.js file that I linked to (if you compile yourself) or in the bundle, find the buildHtml() function and change that line to an empty string.
function buildHtml(c) {
return {
wrapper: '',
menu: '<div class="' + c.menu + '"></div>'
};
}
I don't know if this will have unknown repercussions elsewhere in typeahead, but I just tried it on a page and everything seemed to be working fine.
I have a web application which replaces content. This content has jquery ui check buttons. When I replace the content if a button already exists then don't add it again:
if(!$('label[for=checkWeekM]').hasClass('ui-button'))
$('.checkWeek').button();
If I push the button (its state is checked) and if I replace the content, the button starts locked until the same content is replaced again.
I use Backbone.js to replace the content
jsfiddle
How can I unlock the check button?
You are duplicating id attributes and that leads to bad HTML, bad HTML leads to frustration, frustration leads to anger, etc.
You have this in your template that you have hidden inside a <div>:
<input type="checkbox" class="checkWeek" id="checkWeekM" />
<label for="checkWeekM">L</label>
Then you insert that same HTML into your .content-central. Now you have two elements in your page with the same id attribute and two <label> elements pointing to them. When you add the jQuery-UI button wrapper, you end up with a slightly modified version of your <label> as the visible element for your checkbox; but, that <label> will be associated with two DOM elements through the for attribute and everything falls apart.
The solution is to stop using a <div> to store your templates. If you use a <script> instead, the browser won't parse the content as HTML and you won't have duplicate id attributes. Something like this:
<script id="template-central-home" type="text/x-template">
<div data-template-name="">
<input type="checkbox" class="checkWeek" id="checkWeekM" />
<label for="checkWeekM">L</label>
</div>
</script>
and then this to access the HTML:
content.view = new ContentView({
model: content,
template: $('#template-' + template_name).html()
});
Demo: http://jsfiddle.net/ambiguous/qffsm/
There are two quick lessons here:
Having valid HTML is quite important.
Don't store templates in hidden <div>s, store them in <script>s with a type attribute other than text/html so that browser won't try to interpret them as HTML.
I took a detailed look at your fiddle after you mentioned this problem. The solution I suggested here was more like a quick fix.
If you want to follow the right thing to avoid long term problems and side effects you should consider what is mentioned here. This way your problem is solved and there are no other bugs.
I'm looking to create a form which contains a dynamic number of input text boxes. I would like each text box to form part of an array (this would in theory make it easier for me to loop through them, especially as I won't know the number of text fields that will eventually exist). The HTML code would like something like:
<p>Field 1: <input type="text" name="field[1]" id="field[1]"></p>
<p>Field 2: <input type="text" name="field[2]" id="field[2]"></p>
<p>Field 3: <input type="text" name="field[3]" id="field[3]"></p>
<p>Field 4: <input type="text" name="field[4]" id="field[4]"></p>
<p>Field 5: <input type="text" name="field[5]" id="field[5]"></p>
This data would then be sent to a PHP script and would be represented as an array - or at least, that's the theory.
So my first question is, is this achievable using HTML? Are forms designed to work that way?
If the answer to that is "yes", how would I then go about accessing each of those using jQuery or failing that, plain old JavaScript?
I've attempted to achieve this using the following jQuery code:
someval = $('#field[1]').val();
and
someval = $('#field')[1].val();
and the following JavaScript:
someval = document.getElementById('related_link_url')[1].value;
But I've not had any luck.
Thanks in advance.
Edit:
I should note that from a Javascript point of view, I've had it working where the ID of each element is something like field_1, field_2 etc. However, I feel that if I can achieve it by placing each text box into an array, it would make for tidier and easier to manage code.
Give each element a class and access the group using jQuery:
<p>Field 1: <input type="text" name="field[1]" class="fields"></p>
<p>Field 2: <input type="text" name="field[2]" class="fields"></p>
<!-- etc... -->
jQuery:
$("input.fields").each(function (index)
{
// Your code here
});
This will run the anonymous function on each input element with a classname of "fields", with the this keyword pointing to the current element. See http://api.jquery.com/each/ for more info.
First of all, id attribute cannot contains [ or ] character.
There is lots of ways to get jQuery/plain JavaScript references to these elements. You can use descendant selector:
<fieldset id="list-of-fields">
<!-- your inputs here -->
</fieldset>
$("#list-of-fields input");
document.getElementById("list....").getElementsByTagName("input");
You can also use attribute selector:
$("input[name^=field]");
I'm not sure whether that's the only way but I think in plain JavaScript you'll have to fetch all input elements (document.getElementsByTagName) and then loop through array of these elements and check each element (whether it has name attribute which value starts with field).
I am trying to implement JQuery Autocomplete plugin using Django.
I've been able to wire the thing together and I can actually see the result back in the HTML template.
My problem is that the JQuery Autocomplete CSS doesn't seem to work.
The results I get are not well-formatted/styled, have no background and you cannot even select them.
What is it that I am missing?
I have these three files in my media folder the same folder:
autocomplete.js
dimensions.js
autocomplete.css
In my html template I have the following function:
$(function(){
setAutoComplete("tags", "tagResults", "/taglookup/?query=");
});
My textfield looks like this;
<input type="text" name="tags" value="">
Where do I put the tagResults in my HTML template document? Every time I try to introduce a DIV with id="tagResults", JQuery throws an error.
Any ideas?
