How to load the content of a file into variable using jquery load method?
提问by Yetimwork Beyene
How do I load the content of a file into a variable instead of the DOM using jQuery .load()method?
如何使用 jQuery.load()方法将文件内容加载到变量而不是 DOM 中？
For example,
例如，
$("#logList").load("logFile", function(response){ });
Instead of loading the file into the #logListelement of the DOM, I would like it to load into a variable.
#logList我希望将文件加载到变量中，而不是将文件加载到DOM的元素中。

load()is just a shortcut for $.getthat atuomagically inserts the content into a DOM element, so do:
load()只是$.get自动将内容插入 DOM 元素的快捷方式，所以这样做：
$.get("logFile", function(response) {
var logfile = response;
});

You can use $.get()to initiate a GET request. In the success callback, you can set the result to your variable:
您可以使用$.get()来发起 GET 请求。在成功回调中，您可以将结果设置为您的变量：
var stuff;
$.get('logFile', function (response) {
stuff = response;
});
Please note that this is an asynchronous operation. The callback function will run when the operation is completed, so commands after $.get(...)will be executed beforehand.
请注意，这是一个异步操作。回调函数会在操作完成时运行，所以之后的命令$.get(...)会提前执行。
That's why the following will log undefined:
这就是为什么会记录以下内容undefined：
var stuff;
$.get('logFile', function (var) {
stuff = var;
});
console.log(stuff); //undefined
