blur regex

I'm trying to make sure that the contents of a text box can only be a poistive or negative integer. If not I want to send the focus back to that textbox.

What's wrong with this jquery code which executes for several textboxes? It is allowing non integer values and it sets the focus to the next contron instead of the control with the problem.

$(document).ready(function () {
$(".EOWDPRCYQTextBox").blur(function (event) {
if (this.value.match(/[+,-]{0,1}[0-9]{1,6}/) == null) {
alert("bad");
this.focus;
}
}) // blur
}); // ready

I finally got the regular expression correct as follows:

$(document).ready(function () {
$(".EOWDPRCYQTextBox").blur(function (event) {
if (this.value.toString().match(/^([+-]{0,1})([0-9]{1,6})$/) == null) {
alert("bad");
this.focus;
}
}) // blur
}); // ready

But I still can't get the focus to stay on the same control. How do I do that?

It is quite dangerous to blur, alert, and focus in the same code. Try pasting a wrong value into a field and then click another field. You should use setTimeout to focus so the alert does not trigger the blur of the next field

I am very new to jquery. Can I ask you to modify my code to properly include the setTimeout?

If it works for you then perhaps
No needd to change. Just be aware that the issue exists
