Dear all,

I am using following code to check whether textarea is empty or not:

PHP

$(function () {
        $("#btnSave").click(function () {

var txtaAddress = $("#txtaAddress");
            if ( $(txtaAddress.val()).length <1) {
                alert('Enter address');
                txtaAddress.focus();
                return false;
            }
 }); 
	});

but its not working I have also tried:

PHP

var txtaAddress = $("#txtaAddress");
            if (txtaAddress.val()= "" || txtaAddress.val()= null) {
                alert('Enter address');
                txtaAddress.focus();
                return false;
            }

but its also not working.
Please help me to get rid of this problem.

Solution 1

Try

C#

if (!$("#myTextArea").val()) {
    // textarea is empty
}

Alternately, try

C#

if (!$.trim($("#myTextArea").val())) {
    // textarea is empty or contains only white-space
}
