Thread: onchange does not work

i've a jsp with two html:text elements namely Fromdate and To date. These are intended for user to input datetime values. Next to these text boxes, calendar images are placed. Upon clicking the image the javascript:CSS calendar utility is invoked and it returns the selected date and time which is inserted to these text boxes. Everything was fine, till I added an onchange javascript function to the second text box. This js function calls an ajax method to check whether these values exist in the database. It also checks whether the dates are in correct sequential order. If the JS function returns false, the JSP page should not be forwarded. The functions are returning proper values, but even if the js function return false, the record gets added.

The following is my code:

HTML Code:

<tr>
	       	<td align="left" height="27">   From</td>
	       	<td align="left"><html:text name="myvo" property="fromDate" size="18"/>
	    	             <a href="javascript:NewCssCal('fromDate','ddmmyyyy','dropdown',true)"><img src="img/cal.gif" width="16" height="16" alt="Pick a date"></a>
			</td>
    	</tr>
		<tr>
	       	<td align="left" height="27">     To</td>
	       	<td align="left"><html:text name="myvo" property="toDate" size="18" onchange="return dutyChecker('No','msgarea','2')"/>
	    	             <a href="javascript:NewCssCal('toDate','ddmmyyyy','dropdown',true)"><img src="img/cal.gif" width="16" height="16" alt="Pick a date"></a>
			</td>
    	</tr>

am i missing something here? Or should I change the "onchange" to someother?

Kindly help

How about you try either onkeypress, onkeyup or onkeydown.

I'm not sure onchange is triggered in all browsers for an input text field.

// Json

onkeyup is also not working. See, my intention is to invoke this javascript function on the lostfocus of the second text box. This function should be invoked in all cases ie. when the user fills the text box with keyboard input as well as by clicking on the calendar image. Which is the best option to ensure that this function is invoked regardless of the method of input?

How about adding an onblur to that second text box instead then

Otherwise you might have to bind to many of these event to ensure that the method will get run.

// Json

thanks..used onblur and it made a difference..
