Question

我有一个带有内联javascript的html页面，用于菜单链接。由于它是chrome扩展，我发现内联javascript被禁止。有人可以帮我修改脚本使其有效吗？我在一个标签的论坛中找到了这个代码，但我现在想要将它用于我的chrome扩展。所以基本上我想从<a>标签中删除onclick javascript并转移到javascript外部文件

谢谢

CSS

    ul.tab {
    list-style-type: none;  
    overflow: hidden;
   /* background-color: #f1f1f1;*/
    padding-top: 5px;
    padding-left: 25px;
}

/* Float the list items side by side */
ul.tab li {
  float: left;
  margin-right: 5px;
  margin-left: 5px;
  margin-top: 5px;

}

/* Style the links inside the list items */
ul.tab li a {
    display: inline-block;    
    text-align: center;
    text-decoration: none;
    transition: 0.3s;

}

/* Change background color of links on hover 
ul.tab li a:hover {
    background-color: #ddd;
}*/

/* Create an active/current tablink class */
/*ul.tab li a:focus{
    background-color: tomato;
    color: #fff;
    border:none;
}*/

.tab li a.active {
    background-color: #c30a0a;
    color: #fff;
    border:1px solid #c30a0a;
    border-radius: 5px;
    text-shadow:1px -1px 5px #000;
}

/* Style the tab content */
.tabcontent {
    background: #fff;
    display: none;
    padding: 20px 12px;
    -webkit-animation: fadeEffect 1s;
    animation: fadeEffect 1s;
}

@-webkit-keyframes fadeEffect {
    from {opacity: 0;}
    to {opacity: 1;}
}

@keyframes fadeEffect {
    from {opacity: 0;}
    to {opacity: 1;}
}

的Javascript

    function openTab(evt, linkName) {
    var i, tabcontent, tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
        tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablinks");
    for (i = 0; i < tablinks.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" active", "");
    }
    document.getElementById(linkName).style.display = "block";
    evt.currentTarget.className += " active";
}

Answer 1

尝试这样的事情：

var elements = document.querySelectorAll(selector);

for (var i = 0; i < elements.length; i++) {
    var element = elements[i];
    element.addEventListener("click", function(e) {
      openTab(e, 'Menu'+(i+1))
    });
}
