jQuery gets address bar parameter plug-in (imitates C#)_jquery

May 16, 2016 pm 06:17 PM

复制代码 代码如下:

$.request = (function () {
var apiMap = {};
function request(queryStr) {
var api = {};
if (apiMap[queryStr]) {
return apiMap[queryStr];
}
api.queryString = (function () {
var urlParams = {};
var e,
d = function (s) { return decodeURIComponent(s.replace(/ /g, " ")); },
q = queryStr.substring(queryStr.indexOf('?') 1),
r = /([^&=] )=?([^&]*)/g;
while (e = r.exec(q))
urlParams[d(e[1])] = d(e[2]);

return urlParams;
})();
api.getUrl = function () {
var url = queryStr.substring(0, queryStr.indexOf('?') 1);
for (var p in api.queryString) {
url = p '=' api.queryString[p] "&";
}
if (url.lastIndexOf('&') == url.length - 1) {
return url.substring(0, url.lastIndexOf('&'));
}
return url;
}
apiMap[queryStr] = api;
return api;
}
$.extend(request, request(window.location.href));
return request;
})();

接下来简介绍一下插件的用法。
  我们可以通过 $.request.queryString["key"] 就能获取到地址栏上面key参数。
  大多数情况下我用这个插件来读取一些配置信息。
  我们有时候会在 html 标签中加入一些其他的非HTML属性来作为标志信息,比如我们有时候会写Demo
  这样子我们通过   
    var config = $.request($("#demo").attr("config")).queryString;
    var title = config.title;
  很方便就能读取a上面的配置信息,而且我们不需要给a 添加太多其他的非Html属性。
