Try this.
[HTML]<select name="selectFilter" id="mySelectControl" dojotype="dijit.form.Select">
</select>[/HTML]
var selectControl= dijit.byId("mySelectControl");
if (this.fieldValues!= null && this.fieldValues.length > 0) {
selectControl.addOption({ disabled: false, label: "- Values-", selected: true, value: "- Values-" });
for (icnt = 0; icnt < this.fieldValues.length; icnt++) {
selectControl.addOption(
{ disabled: false,
label: this.fieldValues[icnt],
selected: false,
value: this.fieldValues[icnt]
});
}
}
thank you for replying ,for the code you posted it seems that you use the field values stocked in json file,however, I want to populate the combobox dynamically from my layer.this is my js code ,I want just to know , if I missed something so that is doesn't work .thanx again:) dojo.provide("com.esri.solutions.jsviewer.widgets.DemoWidget");
