Menu
I need to check the selected option of a dropdown on change and give an alert if certain values are selected.
The code:
[CODE]<head>
<script type=”text/javascript”>
function warning(){
var val = document.ThisForm.FLEXValue.value;
if(val == 7||val==6||val==5){
alert(“Warning message.”)
}
}
</script>
</head>
I have also tried:
document.FLEXValue.value
document.FLEXValue.selectedIndex
document.ThisForm.FLEXValue.selectedIndex
document.ThisForm.FLEXValue.options[document.ThisForm.FLEXValue.selectedIndex].value
document.FLEXValue.options[document.ThisForm.FLEXValue.selectedIndex].value
The form:
[CODE]<CFFORM METHOD=”POST” ACTION=”FLEXManager.cfm”>
<TR class=”colMain” style=”font-size=14;”>
<TD colspan=”2″ align=”center”>
<BR>
<b>Select Your New FLEX Percentages Here:</b><BR>
<BR>
DOD <—> PIPP<BR>
<SELECT NAME=”FLEXValue” style=”font-size=16;” onChange=”warning()”>
<cfif GrabEnable.enabled EQ “Y”>
<OPTION value=”7″ <cfif checked EQ “19”>selected</cfif>>4% <—> 0% (code 19)</OPTION>
<OPTION value=”6″ <cfif checked EQ “18”>selected</cfif>>3% <—> 1% (code 18)</OPTION>
<OPTION value=”5″ <cfif checked EQ “17”>selected</cfif>>2% <—> 2% (code 17)</OPTION>
</cfif>
<OPTION value=”1″ <cfif checked EQ “15”>selected</cfif>>0% <—> 3% (code 15)</OPTION>
<OPTION value=”2″ <cfif checked EQ “14”>selected</cfif>>1% <—> 2% (code 14)</OPTION>
<!— <cfif GrabIdle.value LTE 12 AND GrabIdle.value NEQ “”> —>

<OPTION value=”4″ <cfif checked EQ “12”>selected</cfif>>3% <—> 0% (code 12)</OPTION>
</cfif>
</SELECT>
</TD>
</TR>
<TR class=”colMain” style=”font-size=10; font-weight: bold;”>
<TD colspan=”2″ align=”left”>
<UL>
<LI>Changes made today will take effect #DateFormat(GrabActivation.adate,’m/dd/yyyy’)#.</LI>
<LI>If you select Flex Option 17, 18 or 19 you will lose your 45-Day Return privileges.</LI>
</UL>
</TD>
</TR>
<TR class=”colHeader”>
<TD colspan=”2″ align=”right”>
<INPUT TYPE=”SUBMIT” VALUE=”Save Values”>
</TD>
</TR>
<INPUT TYPE=”HIDDEN” NAME=”pacode” value=”#pacode#”>
<INPUT TYPE=”HIDDEN” NAME=”CreateRecord” VALUE=”YES”>
</CFFORM>
But I get the error message document.ThisForm.FLEXValue is null or not an object, and similar messages when I change that part of the function. Please, what am I doing wrong?
Thanks in advance for your help!
