Sencha touch change the color of a specific list item

Question

have a very simple list component, but they want to change the string color of some lines depending on the value / I tried to install tpl, but it does not seem to work. Any help would be appreciated

Ext.create('Ext.dataview.List', {
    id : 'mylist',
    store: myStore,
    tpl: new Ext.XTemplate(
             '<tpl for=".">'
             '    <tpl if="val == 0"><div style="background-color:red">{name}</div></tpl>',
             '    <tpl if="val == 1"><div>{name}</div></tpl>',
             '</tpl>'
    )
});

Answer 1

And, the main error is what you have in your code:

<tpl if="val == 0">

And that is exactly what should be instead:

<tpl if="val === 0">

** Note the three equal signs that you need to add between the two values ​​that you are actually comparing. Therefore, if you usually write

x=y 

Then in the template, which will be

x==y  // (you basically add an extra equal) 

So, a conditional statement like

x==y  //when you're checking if the values are equal

Is becoming

x===y

  '</li>',
   {
        listClasses : function(position, size){
            var classes = [];
            if (position%2===0) {classes.push("even")}
            else                {classes.push("odd")};
            if (position === 1) {classes.push("first")}
            else                {classes.push("last")};

items: [{
    xtype: 'list',
    id: 'patientList',
    store: app.stores.patientList,
    itemTpl: new Ext.XTemplate('<tpl if="overDue14Days &gt; 0"><div class="severeItem"></div></tpl><tpl if="overDue3Days &gt; 0"><div class="mildItem"></div></tpl>', '<div class="listBox">', '<div class="listText">{patientFirstName} {patientLastName}', '<div class="metadata">{numberOfOrders} orders</div>', '</div>', '<div class="listSpacer"></div>', '<div class="deleteItem" id="notMyPatientButton"></div>', '<div class="listArrow"></div>', '</div>'),

Answer 4

• Create your own styles and override sencha touch list-item css

.myList {

  }
.myList .x-list-item {
    position:relative;
    color:#333;
    padding:0em 0em;
    min-height:2.1em;
    display:-webkit-box;
    display:box;
    border-top:1px solid #c8c8c8

}
.myList .x-list-item .brands-row-spon {
    width: 100%;
    background-color: #D8D8D8;
    padding:0.5em 0.8em;
    min-height:2.6em;
}
.myList .x-list-item .brands-row {
    width: 100%;
    min-height:2.6em;
    padding:0.5em 0.8em;
}

• Add cls property of sencha touch list item

new Ext.List({
        fullscreen: true,
        id:'xList',
        itemTpl :xListTpl,
        cls:'myList',
        grouped :true,
        store:  new Ext.data.Store({
        model:'yourModel'
        })
       })

• Add a condition to change the color of a specific list item in your itemTpl list

  var  xListTpl = new Ext.XTemplate(
                                '<tpl for=".">',
                                '<tpl if="isSponsored ==&quot;true&quot;"">',
                                '<div class="brands-row-spon">',
                                '</tpl>',
                                '<tpl if="isSponsored !=&quot;true&quot;"">',
                                '<div  class="brands-row">',
                                '</tpl>',
'</tpl>'
                                );
