在JavaScript中将`return false;`附加到`onClick`事件处理程序

本文介绍了在JavaScript中将`return false;`附加到`onClick`事件处理程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

主要问题:当用户单击anchor标记时摆脱#.我找到了解决方案，在onClick处理程序中添加了return false;

Main Problem : Get rid of # when user clicks on anchor tag. I found a solution for this, which is adding return false; in onClick handler

次要问题:我当前的代码如下

<a href="#" onclick="javaScript:toggleDisplay();" title="Some Title">
    @ViewBag.TotalRecords
</a>

根据我得到的解决方案，我想要这样

And according to solution I got, I want it like this

<a href="#" onclick="javaScript:toggleDisplay();return false;" title="Some Title">
    @ViewBag.TotalRecords
</a>

如何将return false;附加到我的javaScript函数调用中?我可以手动执行此操作，但是有没有简单的方法可以执行此操作.我正在使用jQuery吗?
还有其他方法可以在不修改当前标记的情况下摆脱#吗?

How can I append return false; to my javaScript function call? I can do it manually, but is there any easy way to do this. I am using jQuery?
Is there any other way to get rid of #, without modifying the current markup?

@ViewBag.TotalRecords:这是MVC3 ASP.Net，但与问题无关，因此我没有将其放在标签中.

@ViewBag.TotalRecords: This is a MVC3 ASP.Net thing, but it is not related to the question, hence I didn't put it in the tags.

谢谢

推荐答案

感谢 Phil ，正如我所说的它的.不是只有一种解决方案，而是只有两种解决方案.

Thanks Phil, as I said got something out of it. Got not one but two solutions.

如果我将以下代码添加到js File中，则将处理所有click处理程序(稍后将使其专门针对anchor)

If I add following code to js File, all click handlers are handled (will make it specific for anchor later on)

使用纯JavaScript(不干扰JavaScript )

Using plain JavaScript (Unobtrusive JavaScript)

document.addEventListener('click', function (e) {
   e.preventDefault();
   return false;
});

使用jQuery

$(document).click(function (e) {
    e.preventDefault();
    return false;
});

从某种意义上讲，如果我做了$('a').click(function(e){ e.preventDefault(); });，那么jQuery解决方案与 elclanrs 所建议的解决方案几乎没有什么不同. ，它适用于anchor，但是我修改了DOM并向其中添加了新的anchor，单击此锚点会导致查询字符串中的#.

The jQuery Solution is little different than the one suggested by elclanrs, in the sense, if I do $('a').click(function(e){ e.preventDefault(); });, it works for anchor, but I modify my DOM and add new anchor to it, click on this anchor causes # in query string.

以上解决方案使所有点击都通过了处理程序，即使我不希望这样做.由于以href作为网址的正常anchor无法正常工作，因此这是有效的解决方案

The above solution causes all the clicks to go through the handler, even which I don't want. Because of this normal anchor with href as url were not working, so this is the working solution

$("a").live("click", function (e) {
   if ($(this).attr("href") != "#") return;
   e.preventDefault();
   return false;
});

希望这对其他人有帮助.

Hope this helps some one else.
