Or not using jQuery:

To get the href of the link:

要获取链接的 href：

var href = $('#Anchor').attr('href');

To get the HTML inside:

要获取其中的 HTML：

var html = $('#Anchor').html();

#Anchoris the CSS-format selector that means, "Select the element with the ID 'Anchor'."

#Anchor是 CSS 格式选择器，意思是“选择 ID 为 'Anchor' 的元素。”

You can get the specific query parameter of url by using following code:

您可以使用以下代码获取 url 的具体查询参数：

Javascript

Javascript

<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>

<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>

and here is the usage of this function:

这是此功能的用法：

alert(getAnchorValue('Anchor', 'myTag'));

alert(getAnchorValue('Anchor', 'myTag'));

JQuery

查询

<script type="text/javascript">
    ; (function ($) {
        $.extend({
            getAnchorValue: function (name, url) {
                function getQueryStringParams() {
                    var parameters = {}, e, a = /\+/g, r = /([^&=]+)=?([^&]*)/g,

Usage:

用法：

alert($.getAnchorValue('myTag', $('#Anchor').attr('href')));

alert($.getAnchorValue('myTag', $('#Anchor').attr('href')));

EDIT: I have editted my answer and also added the jquery code for getting the querystring parameter
