Code Snippet for validating the textbox, dropdownlist, and radiobuttonlist in ASP.NET page using Jquery.
To check Textbox value:
txtName is the textbox id:
[sourcecode language="javascript"] if ($.trim($(“#txtName”).val()).length == 0) { //Enter a name } [/sourcecode]
To check Whether entered value is number or not:
$.isNumeric(value) method can be used to check for number
[sourcecode language="javascript"] var age = $.trim($(“#txtAge”).val()); if ($.isNumeric(age)) { //Entered number is Numeric } [/sourcecode]
To check whether any radio button is checked:
rdbGender is the Radiobuttonlist id:
[sourcecode language="javascript"] if ($(“#rdbGender input:checked”).length == 0) { //Gender is not selected } [/sourcecode]
To check whether any dropdownlist value is checked:
ddlQualification is the Dropdownlist id:
[sourcecode language="javascript"] if ($(“#ddlQualification option:selected”).val() == 0) { //Qualification is not selected } [/sourcecode]
