I have a page with a table having some <input type="text"> fields. I have a button next to each field. I allow user to change the text of input fields. But when the user click the button next to input field, the corresponding input field's value need to be restored to default (previous) value.

I tried to make an array with index as input field's name. This array can store default values, and can be retrieved easily and restored to their corresponding fields. I tried to do this using keyup(function(), but I know that this triggers each time key is pressed.

Here is my HTML;

<input class="zx" type="text" name="qwer" value="Google" /><button class="cncl">X</button><br />
<input class="zx" type="text" name="qwer" value="Yahoo" /><button class="cncl">X</button><br />
<input class="zx" type="text" name="qwer" value="Bing" /><button class="cncl">X</button><br />
<input class="zx" type="text" name="qwer" value="Ask" /><button class="cncl">X</button><br />

Here is the fiddle.

How can I restore the default values to the fields?

• javascript
• jquery
• forms
• restore

• what do you mean by previous value? the original value when the input was created – Arun P Johny Commented Mar 24, 2014 at 11:01
• Why not just $('form')[0].reset()? – putvande Commented Mar 24, 2014 at 11:06
• why dont you use placeholder attribute and do your form processing after checking if the submitted value has value or not – Viswanath Polaki Commented Mar 24, 2014 at 11:57

You can use the defaultValue property of the input element

$('.cncl').click(function(){
    $(this).prev().val(function(){
        return this.defaultValue;
    })
})

Demo: Fiddle

Try this, use .attr('value') to get the default value:

$('.cncl').on('click', function () {
    $(this).prev().val($(this).prev().attr('value'));
});

I have done something similair in the past. I stored the default value in an attribute of the html-tag itself.

<input class="zx" type="text" name="qwer" default-value="Google" value="Google" />

When you like to restore it you can execute

$('selector').val($('selector').attr('default-value'));
