javascript - 从链接中删除 JavaScript

Question

链接代码如下:

<td class="buttonColumn">
<a href="javascript:confirmDialog('Are you sure you want go?', 'http://google.com');" class="actionButtonNew">Leave to Google</a>
</td>

<td class="buttonColumn">
<a href="javascript:confirmDialog('Are you sure you want go?', 'http://yahoo.com');" class="actionButtonNew">Leave to Yahoo</a>
</td>

页面上有多个格式完全相同的按钮也需要更改。我在想这样的事情:

var fix = document.getElementsByClassName('actionButtonNew');
for (var i=0; i<fix.length; i++) {

我不知道如何完成代码。我试过这个:

var fix = document.getElementsByClassName('actionButtonNew');
for(var i = 0; i < fix.length; i++) {
    try {
        var l = fix[i];
        var h = fix[i].parentNode.getElementsByClassName('actionButtonNew')[0].href.replace("javascript:confirmDialog('Are you sure you want to go?',", "");
        l.href = h;
    } catch(e) {}
}

我知道这非常困惑和糟糕。它确实将链接更改为:'http://google.com ')；

所以我想我可能走在正确的道路上。请帮我。提前致谢!

这里有一个想法:不要处理在某些边缘情况下必然会中断的困惑正则表达式，而是将 confirmDialog 替换为无需确认即可重定向的函数:

window.noConfirm = function(m, url) {
    document.location.href = url;
}

var fix = document.getElementsByClassName('actionButtonNew');
for (var i = 0; i < fix.length; i++) {
    fix[i].href = fix[i].href.replace('confirmDialog', 'noConfirm');
}

另一个有趣的想法:更改它调用一个立即修复链接的函数，然后触发点击:

window.fixMe = function(m, url) {
    this.href = url;
}

var linksToFix = document.getElementsByClassName('actionButtonNew');
for (var i = 0; i < linksToFix.length; i++) {
    window.a = linksToFix[i];
    linksToFix[i].href = linksToFix[i].href.replace('confirmDialog(', 'fixMe.call(a, ');
    linksToFix[i].click();
}
