I have here Jquery code with ajax/json. First i will discuss the flow. I have 3 textboxes, my item
textbox pass it's value to auto-complete.php through ajax to get it's details. The return value is post or place into mode
textbox. And if the post value is 1 or 2 the number
textbox should change is css into display:none
. But the problem this not working, I set the number
textbox into readonly. The change function is working when I change directly the value of number
textbox. Why isn't working when the value is post value?
<script>
$(document).ready(function() {
$("#number").css("display","none");
$(document).on('change','#mode',function(){
if($("#mode").val() =="1"){
$("#number").css("display","");
} else if($("#mode").val() =="2"){
$("#number").css("display","");
} else {
$("#number").css("display","none");
}
return true;
});
});
</script>
<input name="item" id="item" type="text"/>
<input name="mode" id="mode" type="text"/>
<input name="number" id="number" type="text" readonly />
<script type="text/javascript">
$(document).ready(function()
{
$('#item').change(function()
{
var item= $("#item").val();
$.ajax({
type: "POST",
url: "autocomplete-ajax.php",
data :"item="+item,
dataType:'json',
type:'POST',
success:function(data){
var mode=data.mode;
//send to element ID
$('#mode').val(mode);
}
});
return false;
});
});
</script>
When you change the value using JavaScript it won't trigger events.
A simple fix is to trigger the event yourself after you update the value.
success:function(data){
var mode=data.mode;
//send to element ID
$('#mode').val(mode).change();
/* OR */
$('#mode').val(mode).trigger('change');
}
