How can I solve this using Knockout JS? - html

Question

I have the following code, I am trying to get an id in the SPAN and it is not accepting values in any type of tag that is located inside ....
<div class="col-lg-12 col-md-12" id="contenedorListaTarea">
<ul class="nav nav-tabs align-items-lg-start mb-1" data-bind="foreach: loterias">
<li class="nav-item" name="loteria" data-bind="click:namerjarClickLoteria">
<a class="nav-link fontSizeTab" data-bind="text: nombre,style: { backgroundColor: color},attr:{id:id+nombreCorto}">
<span data-bind="attr:{id:nombreCorto}" >0.00</span>
</a>
</li>
</ul>
</div>

Answer 1

If I understand you correctly your problem is that any tag placed in <a> tag is to being rendered. The reason for that to happen is that your <a> tag is using text: nombre binding which is replacing anything you have put inside it.
I removed that binding and <span> started to appear in it with working attr binding.
var viewModel = function() {
this.loterias = ko.observableArray([
{
nombre: 'test',
color: 'red',
id: 'test-id',
nombreCorto: 1,
namerjarClickLoteria: function(){
}
},
{
nombre: 'test',
color: 'green',
id: 'test-id',
nombreCorto: 2,
namerjarClickLoteria: function(){
}
}
]);
return this;
}
ko.applyBindings(viewModel(), $('#contenedorListaTarea')[0]);
