ajax getScript() methodsyntax

Syntax: jQuery.getScript(url,success(response,status))
Parameters:
| Parameters | Description |
| url | The URL string to be requested. |
| success(response,status) | Optional. Specifies the callback function to be executed after the request is successful. Additional parameters: response - contains the result data from the request status - contains the status of the request ("success", "notmodified", "error", "timeout" or "parsererror") |
Description: This function is the abbreviated Ajax function, equivalent to: $.ajax({url: url, dataType: "script",success: success}); The callback function here will Pass in the returned JavaScript file. This is usually not very useful since the script has already been run by then. Loaded scripts are executed in the global environment and therefore can reference other variables and use jQuery functions. For example, load a test.js file, which contains the following code: $(".result").html("<p>Lorem ipsum dolor sit amet.</p>"); By referencing the file name, You can load and run this script: $.getScript("ajax/test.js", function() {alert("Load was performed.");});
