Html anchor tag onclick() and href execute simultaneously
提问by CheeHow
Similar to HTML anchor link - href and onclick both?post, mine is:
类似于HTML 锚链接 - href 和 onclick 两者？帖子，我的是：
<a href="/tmp/download.mp3" onclick="update();">Download link</a>
The update()method would send another HTTP GET method to the server to update the which file has been downloaded and update the database. From the HTML code, there are 2 GET requests being triggered together and only ONE will get the response (the href download response) from the server. The update()is not being executed. Is there any method that i can get both GET methods to be executed? Javascript and Jquery suggestions are welcomed!
该update()方法将向服务器发送另一个 HTTP GET 方法以更新已下载的文件并更新数据库。从 HTML 代码来看，有 2 个 GET 请求被一起触发，只有一个会从服务器获得响应（href 下载响应）。在update()没有被执行。有什么方法可以让我同时执行两个 GET 方法？欢迎 Javascript 和 Jquery 建议！

Forget about the hrefand just do it all in the click function. You can navigate to another page after the update is complete. Here is my JQuery suggestion:
忘记href，只需在点击功能中完成所有操作。更新完成后，您可以导航到另一个页面。这是我的 JQuery 建议：
HTML
HTML
<a id="download" href="/tmp/download.mp3">Download link</a>
JavaScript (with JQuery)
JavaScript（使用 JQuery）
$("#download").click(function(e){
e.preventDefault();//this will prevent the link trying to navigate to another page
var href = $(this).attr("href");//get the href so we can navigate later
//do the update
//when update has finished, navigate to the other page
window.location = href;
});
NOTE: I added in an idfor the atag to ensure it can be selected accurately via JQuery
注意：我添加了一个idfora标签以确保它可以通过 JQuery 准确选择
