Question

I have a javascript function that checks a textbox value and return either true or false regarding it value.

I have several textboxes to check:

<asp:textbox id="txt1" class="tocheck" runat="server />
<asp:textbox id="txt2" class="tocheck" runat="server />
<asp:textbox id="txt3" class="tocheck" runat="server />

and when I press the submit button (Linkbutton1) I check all their values:

$('#LinkButton1').click(function () {
    var error = false;
    $.each($('.tocheck'), function (i, v) {
        error =  check($(v).val(), $(this));
    });
    return error;
});

If one of the calls return true the overall validation must be considered failed and the true value must be kept.

So what I want is prevent the error variable to be set to false when it’s already previously set to true.

Is there any operator or function that controls this?
Thank you.

Answer 1

$('#LinkButton1').click(function () {
    var error = false;
    $.each($('.tocheck'), function (i, v) {
        if (!error) {
            error =  check($(v).val(), $(this));
        }
    });
    return error;
});

You can also return false in the function to break the each. More information in the documentation : http://api.jquery.com/jQuery.each/
