How to reset a form using Javascript Solutions

hi Experts,

I have a form with three fields Timeline, from and to date. I need to implement Reset to Defaults functionality on this (Actually I already have a reset condition on the form.) The problem I am facing is :
* Once the user hits Update, I cant reset the form. Prior to clicking update, form resets perfectly fine. but once the user hits update and new page loads, it doesnt have the default(Monthly ins this case) in the timeline section.

Is it doable with javascript?If yes, then how ? :(

<div class="sidebar-panel" style="border:5px solid #99CCFF; width:145px; padding:2px; background:white;">
<div style="font-weight:bold; color:#000000 ">Selection</div>
<div style="font-weight:100; line-height:normal; font-size:9px; margin:5px 0;"> Select from the options below and then click on Update Chart.</div>
 <form:form commandName="sideForm">
<div style="font-weight:bold; color:#000">Timeline</div>
 
<div align="center" style="margin:0 0 5px 0; ">
<div style="margin:0 0 5px 0;"><form:select path="timeline" items="${timeline}" id="tm"/></div>
</div>
<div style="color:black;">
<div class="tofrom">From:</div>
<div class="calimg"><img src="/analytics/static/images/CAL.PNG" name="Calendar" width="18" height="18" id="Calendar" onClick="displayDatePicker('from_date');" /></div>
<form:input path="startDt" id="from_date" size="7" maxlength="10" />
</div>
<div style="color:black;">
<div class="tofrom">To:</div>
<div class="calimg"><img name="Calendar" src="/analytics/static/images/CAL.PNG" width="18" height="18" id="Calendarm" onClick="displayDatePicker('to_date');" /> </div>
 
<form:input path="endDt" id="to_date" size="7" maxlength="12" />
 
</div>
<div style="font-wight:bold; color:#000">*15 Month Max Per Chart</div>
<br />
<div style="float:left; font-size:9px; font-weight:lighter; padding:0; color:black; color:blue"><a href="#" style='text-decoration: none; color:#2525FF;' onClick="document.forms[0].reset();return false">Reset To Defaults</a></div>
<h6 style="font-size:4px; font-wight:lighter; float:right;">
<div style="width:60px; font-size:.5em; font-weight:lighter; background: #FFFFFF ">
<input type="submit" value="Update Chart" onClick="return validateDates()"/>
</div>
</h6>
<div style="clear:both;"></div>
</form:form>
</div>

Instead of:
onClick="document.forms[0].reset();return false">Reset To Defaults
 
try:
onClick="$("option:contains('Monthly')").attr("selected","selected");return false">Reset To Defaults

If you have more than one timeline select list, then give each list an id - ex::

<select id="select1">
	<option value="daily">Daily</option>
	<option value="weekly">Weekly</option>
	<option value="monthly">Monthly</option>
</select>
 
<select id="select2">
	<option value="daily">Daily</option>
	<option value="weekly">Weekly</option>
	<option value="monthly">Monthly</option>
</select>
 
Then use that id on the onclick event - ex:
$("#select1 option:contains('Monthly')").attr("selected","selected");
 
will select Monthly only for select with id="select1"

Hi hielo,

Thanks for the help, it Didnt work :(

This is what I did.

<a href="#" style='text-decoration: none; color:#2525FF;' onClick="$("option:contains('Monthly')").attr("selected","selected");return false">Reset To Defaults</a>

Hi Hielo,

Actually the timeline dropdown list values are coming from a backend javacode. I havent hardcoded them as HTML <Select> <Option>

what you posted has syntax errors. You onclick should start and end with apostrophes, NOT double quotation marks since the value within the onclick already uses double quotation marks. Copy and paste this:

<a href="#" style='text-decoration: none; color:#2525FF;' onClick='$("option:contains('Monthly')").attr("selected","selected");return false'>Reset To Defaults</a>

sorry, you still need to escape the apostrophes around 'Monthly'. Copy and paste this:

<a href="#" style='text-decoration: none; color:#2525FF;' onClick='$("option:contains(\'Monthly\')").attr("selected","selected");return false'>Reset To Defaults</a>

I am sorry, didnt work either (

I am getting an error at the bottom of IE, saying done with errors on page. I have attached the snap shot

Look at my previous post. You probably missed it!

Hi hielo,

I am sorry if I made some mistake but this is the code I used:

<a href="#" style='text-decoration: none; color:#2525FF;' onClick='$("option:contains(\'Monthly\')").attr("selected","selected");return false'>Reset To Defaults</a>

onClick is starting and ending with apostrophes :(

change both of the slash apostrophes:
\'...\'

to:
slash double quotes
\"...\"

Hey hielo,

Thanks a lot Sir. :) Sorry I kept bugging you for long. Can you please help me in understanding the code you gave? I am very new to this.

Also, will this code, reset the defaults on From and To fields?

>> Did it work?
yes Sir, perfectly fine :) Thanks a ton.

>> I havent hardcoded them as HTML <Select> <Option>
I meant, those values are stored in backend bean and fetched on the fly. but yes I saw the generated HTML, its <OPTION> :)

>> $("#from_date").val(\"ALPHA\");
so instead can I supply the variable I am using to store a default value?

>>so instead can I supply the variable I am using to store a default value?
try it! You learn better by making mistakes and banging your head against the wall :)

Thanks a lot Sir :-)
