Reset input value after alert - Javascript

rated 0 times [ 2] [ 1] / answers: 1 / hits: 46418 / 12 Years ago, wed, june 6, 2012, 12:00:00

I have a simple input box where if the number is higher than 2, a popup message will appear.

Here is the code I am using, however I already have an onkeyup command on the input for something else, so I hope that won't be a problem

HTML:

<input id=jj_input23 type=text value='' onkeyup='changeTransform()' />

Javascript:

if(jj_input23 > 2) {

    alert(Making the scale higher than 2 will make the preview too big);

    document.getElementById('jj_input23').value();

}

After the aler message has been displayed, and the user has clicked Ok, I want the input text to reset. How can I do this?

Thanks in advance

if(jj_input23 > 2) {

    alert(Making the scale higher than 2 will make the preview too big);

    document.getElementById('jj_input23').value = ;

}

If you're using jQuery then you almost got it:

$('#jj_input23').val();
