使用 JavaScript 变量代替 jquery 选择器

Question

instead of $('#hello').load("mysql.php"); ,where the selector is a html element , is there any way i can use .load() to store the result in a javascript variable something like var res; $('#res').load("mysql.php"); var res; $('#res').load("mysql.php");

Answer 1

You can make use of the callback, and store the response to a variable. However you do have the asynchronous nature of this function to bare in mind, meaning the res variable will be undefined until you get the response.

var res;
$('#res').load( "mysql.php", function( response, status, xhr ) {
    res = response;
});
