在超链接上调用javascript函数点击 [英] call javascript function on hyperlink click

问题描述

我在ASP.NET的c＃代码隐藏文件中动态创建超链接。我需要在客户端点击时调用JavaScript函数。我怎么做到这一点？

I am dynamically creating a hyperlink in the c# code behind file of ASP.NET. I need to call a JavaScript function on client click. how do i accomplish this?

推荐答案

Neater仍然，而不是典型的href =＃或 href =javascript：void或 href =whatever，我想这个更有意义：

Neater still, instead of the typical href="#" or href="javascript:void" or href="whatever", I think this makes much more sense:

var el = document.getElementById('foo');
el.onclick = showFoo;


function showFoo() {
  alert('I am foo!');
  return false;
}

<a href="no-javascript.html" title="Get some foo!" id="foo">Show me some foo</a>

如果Javascript失败，会有一些反馈。此外，不稳定的行为（在 href =＃的情况下跳页，在 href =的情况下访问同一页面）已被淘汰。

If Javascript fails, there is some feedback. Furthermore, erratic behavior (page jumping in the case of href="#", visiting the same page in the case of href="") is eliminated.
