I have this in my HTML:
<script id="tpl" type="text/template">
<div data-id="" class="line">
...
</div>
</script>
In JS I'm getting that template to add it into the HTML, then set each a data attribute, as:
$('.add-line').on('click', function(){
var tpl = $('#tpl').html()
$(tpl).data('id', 'TEST')
$(tpl).attr('data-id', 'TEST')
$('.target').append(tpl)
})
But none of these added have any data-id. What am I doing wrong?
Try this
$('.add-line').on('click', function() {
var tpl = $($('#tpl').html()).map(function() {
if ($(this).hasClass('line')) {
$(this).attr('data-id', 'TEST');
}
return this;
});
$('.target').append(tpl);
})<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script id="tpl" type="text/template">
<div data-id="" class="line">Test</div>
</script>
<a class="add-line">Add line</a>
<div class="target"></div>Or more shorter version with temporary div
$('.add-line').on('click', function(){
var content = $('#tpl').html(),
tpl = $('<div />').html(content).find('.line').attr('data-id', 'TEST');
$('.target').append(tpl);
})<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script id="tpl" type="text/template">
<div data-id="" class="line">Test</div>
</script>
<a class="add-line">Add line</a>
<div class="target"></div>
