将 jquery 转换为 java 脚本

发布于 2024-10-31 21:29:37 字数 1829 浏览 0 评论 0原文

我有这个用 jQuery 制作的脚本,我用它来在我的页面上显示/隐藏 div。 我真的需要它纯粹用 JavaScript 制作,但我不知道如何做到这一点。 有人可以帮助我吗??? 我想我需要一个转换器什么的。 。 。

$("#optiuni").children().click(function(){
    $("#" + $(this).attr('name')).show().siblings().hide();
    /*Gives the  link-activ class to the link that i clicked an link-inactive to all others*/
    $(this).attr('class','link-activ').siblings().attr('class','link-neactiv');
});
/*this makes shure that the first option from my list is active  incarcarea paginii*/
$("#optiuni li.prima").children().click();

标记示例:

<div id="lista">
  <ul id="optiuni">
    <li id="titlu-lista-p"> <p class="listname-t">Past Events </p></li>

    <li name="opt-1" class="prima"><a href="#"><p class="listdata">28.02.2011</p><p class="listname">TABU Oscar Party</p> </a></li>

    <li name="opt-2" ><a href="#"><p class="listdata">24.03.2011</p><p class="listname">Cheese & Wine</p></a></li>
    <li name="opt-8"><a href="#"><p class="listdata">08.04.2011</p><p class="listname">George Baicea</p></a></li>
  </ul>
</div>

<div class="centru">
  <div id="continut" >
    <div id="opt-2" class="galerie" style="background-color: black;">
      <iframe id="gal" src="cheese/index.html"></iframe>
    </div>
    <div id="opt-1" class="galerie" style="background-color: black;">
      <iframe  src="tabu/index.html"></iframe>
    </div>

    <div id="opt-8" class="galerie" style="background-color: blue;">
      <iframe   src="no-ev/index.html"></iframe>
    </div>
  </div>
</div>

I have this script made with jQuery which I am using to show / hide divs on my page.
I really need it to be made purely in JavaScript and I have no idea how to do this.
Could anyone help me ???
I think I need a converter or something . . .

$("#optiuni").children().click(function(){
    $("#" + $(this).attr('name')).show().siblings().hide();
    /*Gives the  link-activ class to the link that i clicked an link-inactive to all others*/
    $(this).attr('class','link-activ').siblings().attr('class','link-neactiv');
});
/*this makes shure that the first option from my list is active  incarcarea paginii*/
$("#optiuni li.prima").children().click();

Sample markup:

<div id="lista">
  <ul id="optiuni">
    <li id="titlu-lista-p"> <p class="listname-t">Past Events </p></li>

    <li name="opt-1" class="prima"><a href="#"><p class="listdata">28.02.2011</p><p class="listname">TABU Oscar Party</p> </a></li>

    <li name="opt-2" ><a href="#"><p class="listdata">24.03.2011</p><p class="listname">Cheese & Wine</p></a></li>
    <li name="opt-8"><a href="#"><p class="listdata">08.04.2011</p><p class="listname">George Baicea</p></a></li>
  </ul>
</div>

<div class="centru">
  <div id="continut" >
    <div id="opt-2" class="galerie" style="background-color: black;">
      <iframe id="gal" src="cheese/index.html"></iframe>
    </div>
    <div id="opt-1" class="galerie" style="background-color: black;">
      <iframe  src="tabu/index.html"></iframe>
    </div>

    <div id="opt-8" class="galerie" style="background-color: blue;">
      <iframe   src="no-ev/index.html"></iframe>
    </div>
  </div>
</div>

以下是如何根据评论中的链接到的标记执行此操作的示例,如下您可以根据 jQuery 版本做出一些假设,但当您看到标记时这些假设并不成立。

jsFiddle 的实例

// IE sucks
function addEvent(el, name, handler) {
  if (el.addEventListener) {
    el.addEventListener(name, handler, false);
  } else if (el.attachEvent) {
    // Make sure "this" references the element we're adding the event handler to
    el.attachEvent('on' + name, function() { handler.call(el, window.event); });
  }
}

function eachElementSibling(el, func) {
  var childNodes = el.parentNode.childNodes;
  for (var i = 0, sibling; sibling = childNodes[i]; i++) {
    if (sibling.nodeType !== 1 || sibling === el) {
      continue;
    }
    func(sibling);
  }
}

function activateLink() {
  var elToShow = document.getElementById(this.getAttribute('name'));
  elToShow.style.display = '';
  eachElementSibling(elToShow, function(s) { s.style.display = 'none'; });
  this.className = 'link-active';
  eachElementSibling(this, function(s) {
    if (s.getAttribute('name')) { s.className = 'link-neactiv'; }
  });
}

var items = document.getElementById('optiuni').getElementsByTagName('li');
var initialItem = null;
for (var i = 0, item; item = items[i]; i++) {
  // Need to filter, as non-link items are also present in the list
  if (item.getAttribute('name')) {
    addEvent(item, 'click', activateLink);
    if (item.className === 'prima') {
      initialItem= item;
    }
  }
}
if (initialItem) {
  activateLink.call(initialItem)
}

Here's an example of how you could do this based on the markup you linked to in your comment, as there are some assumptions you could make based on the jQuery version which don't hold when you see the markup.

jsFiddle with a live example.

// IE sucks
function addEvent(el, name, handler) {
  if (el.addEventListener) {
    el.addEventListener(name, handler, false);
  } else if (el.attachEvent) {
    // Make sure "this" references the element we're adding the event handler to
    el.attachEvent('on' + name, function() { handler.call(el, window.event); });
  }
}

function eachElementSibling(el, func) {
  var childNodes = el.parentNode.childNodes;
  for (var i = 0, sibling; sibling = childNodes[i]; i++) {
    if (sibling.nodeType !== 1 || sibling === el) {
      continue;
    }
    func(sibling);
  }
}

function activateLink() {
  var elToShow = document.getElementById(this.getAttribute('name'));
  elToShow.style.display = '';
  eachElementSibling(elToShow, function(s) { s.style.display = 'none'; });
  this.className = 'link-active';
  eachElementSibling(this, function(s) {
    if (s.getAttribute('name')) { s.className = 'link-neactiv'; }
  });
}

var items = document.getElementById('optiuni').getElementsByTagName('li');
var initialItem = null;
for (var i = 0, item; item = items[i]; i++) {
  // Need to filter, as non-link items are also present in the list
  if (item.getAttribute('name')) {
    addEvent(item, 'click', activateLink);
    if (item.className === 'prima') {
      initialItem= item;
    }
  }
}
if (initialItem) {
  activateLink.call(initialItem)
}
