网页中联系我们代码怎么用按钮实现

怎么不换一个思路呢？用a页面获取b页面有点击按钮的标签对象，再获取onclick属性的值，得到了函数

再运行这个函数就可以了呀。要想用js控制按钮的点击，我也找了很久几乎是没这个功能。

JavaScript求解。

$('#navigation li')获取id='navigation'.的html元素下的所有li标签对象的引用的集合

each方法是遍历集合将集合中的对象作为function的this指针, 执行function.

$('#navigation li').each(function(){...});的等效的原生js代码大约是这样:

var element = document.getElementById('navigation');

var collection = element.getElementsByTagName('li');

for (var child in collection){

(function(){

//do something

}).apply(child);

}

根据上述代码可知, 在function方法中的this指针引用的是ul#navigation的子节点li标签对象.

$('a', this)则是引用li标签的子节点a标签

楼上几位估计都是来完成任务的...

什么是JS代码？

你所谓的HTML是英文Hypertext Markup Language的简写，说明了说是标签，还不能称之为语言。一般是一个开始标签与一个结束标签组成！是网站代码的基础！如果是你网页不会这个肯定办不了事！

JS的全称是javascript，是一门内嵌语言，是写在网页中以实现网页客户端交互。当然服务端JS也还是有的！一般是以script language="javascript"/script包括中的，也就是说以上还是一个HTML标签，但里边所写的内容却是javascript,浏览器会自动解释！当然这个语言就是为了网页的动态而出现的！

所以两者是有很大区别的！你可以这样理解：HTML是网页基础，而JAVASCIRPT是为了补充HTML的静态网页而出现的一个HTML或说浏览器内置语言！实现网页动态效果！

求js这段代码

JS 或php如何实现 “ 您的位置：站点首页 ->联系我们 -> 联系方法”

JS获取title。。。没有这样做的。

你这个功能叫面包屑导航。

前台的面包屑是根据当前的分类的id也就是catid来定位当前在哪块，然后依次查找到父栏目。

简单的就是递归实现了。举个例子，如果你打开的页面时 ”新闻“栏目下面的“中国新闻”

那么你肯定可以获取到中国新闻的catid，有catid就肯定可以查到栏目名称了，然后查找”中国新闻“的父栏目，也就是”新闻“，这样都查到了，组合一下 就是 新闻-中国新闻。如果分的级很多就得用递归了，循环查找当前栏目的父栏目，代码思路是，判断当前父栏目是否还有父栏目，如果有就调用本身，无限查找下去，就查找到顶头了。。。
