我在aspx页面中有一个锚点链接,如:
<a id="Anchor"class="myAnchor" href="Myproject/Mypage.aspx?myTag=asp">Go</a>
我需要使用jquery来访问“myTag”值。如何做到这一点?

$(function(ready){
alert($('#Anchor').attr('href')); // prints Myproject/Mypage.aspx?tag=asp
alert($('#Anchor').text()); // prints Go
});

你可以这样做:
var myTag = $('#Anchor')[0].search.split('=')[1];
示例: http://jsfiddle.net/B6GYB/
或者不使用jQuery:
var myTag = document.getElementById('Anchor').search.split('=')[1];

获取链接的href:
var href = $('#Anchor').attr('href');
要获取HTML内容:
var html = $('#Anchor').html();
#Anchor
是CSS格式选择器,表示“选择ID为'Anchor'的元素。”

您可以使用以下代码获取url的特定查询参数:
<强>的Javascript 强>
<script type="text/javascript"> function getAnchorValue(anchorId, key) { var href = document.getElementById(anchorId).getAttribute('href'); var pageQuerySearch = new PageQuery(href.split('?')[1]); return unescape(unescape(pageQuerySearch.getValue(key))); } function PageQuery(query) { if (query.length > 1) {this.q = query; } else { this.q = null; } this.keyValuePairs = new Array(); if (this.q) { for (var i = 0; i < this.q.split("&").length; i++) { this.keyValuePairs[i] = this.q.split("&")[i]; } }; this.getValue = function (s) { for (var j = 0; j < this.keyValuePairs.length; j++) { if (this.keyValuePairs[j].split("=")[0] == s) { return this.keyValuePairs[j].split("=")[1]; } } return false; }; } </script>
以下是此功能的用法:
alert(getAnchorValue('Anchor','myTag'));
<强> JQuery的强>
<script type="text/javascript"> ; (function ($) { $.extend({ getAnchorValue: function (name, url) { function getQueryStringParams() { var parameters = {}, e, a = /\+/g, r = /([^&=]+)=?([^&]*)/g, d = function (s) { return decodeURIComponent(s.replace(a, " ")); }, q = url ? url.split('?')[1] : window.location.search.substring(1); while (e = r.exec(q)) { parameters[d(e[1])] = d(e[2]) }; return parameters; } if (!this.params) this.params = getQueryStringParams(); return this.params[name]; } }); })(jQuery); </script>
用法:
alert($。getAnchorValue('myTag',$('#Anchor')。attr('href')));
