截取url参数

链接
'<a href="/admin/base/projectManagement/externalassociation.html?id='+rowData.id+'&name='+ encodeURI(encodeURI(rowData.name)) +'"  style="margin-right:8px;display: inline-block;padding: 5px 7px!important;border-radius: 5px;" id="create-project2'+rowData.id+'" class="easyui-linkbutton button-blue-model nav-link iframeify font-teal"  title="外部关联工具" close="true"  >外部关联工具 </a>';
function getQueryString(name){
    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
    var r = window.location.search.substr(1).match(reg);
    if (r != null) return decodeURI(r[2]);
    return null;
};
调用=>
getQueryString("key")

假如参数有汉字
decodeURI(decodeURI(getQueryString("realName")));
