Cascading AutoComplete


Go to solution Solved by jhanajc,

Question

Hi, 

 

Using the code below I am populating a text field on a submission form which is then used as a Parent Field on a Cascading AutoComplete Virtual field triggered when the Date field changes.

This technically works but I find that the AutoComplete field does not update immediately unless I physically visit the parent field and make a keystroke (say a type space at the end of the value).

How can I force the Cascading AutoComplete field to update immediately?

Thanks!

 

<script type="text/javaScript">

function concatenate()
{
mydate = document.getElementsByName("InsertRecordDate")[0].value;
document.getElementsByName("InsertRecordDate_With_ID")[0].value = list_id+mydate;
}

var list_id = document.getElementsByName("InsertRecordListing_ID")[0].value;
var mydate = document.getElementsByName("InsertRecordDate")[0].value;

document.getElementsByName("InsertRecordDate_With_ID")[0].value = list_id+mydate;

document.getElementsByName("InsertRecordDate")[0].onchange = concatenate;

</script>

 

Further information:  I suspect it might be that the onchange event is not triggering on the receiving field (Date_With_ID) because the value is being script updated and not manually typed.

Trying to find a way of forcing the change event to occur. Any advice appreciated thanks!

The following code in bold has the desired effect. It triggers a change event on the field after it has been updated by script:

 

var changeEvent = document.createEvent("HTMLEvents");

function concatenate()
{
mydate = document.getElementsByName("InsertRecordDate")[0].value;
document.getElementsByName("InsertRecordDate_With_ID")[0].value = list_id+mydate;


changeEvent.initEvent("change", true, true);
document.getElementsByName("InsertRecordDate_With_ID")[0].dispatchEvent(changeEvent);

}
