在 html 通过js 获取查询参数

<script type="text/javascript">
    var getParameters = function() {
        var search = window.location.search;
        var obj = {};
        if (search != '') {
            // window.location.search '' or start with '?'
            search = search.substring(1);
            var keypairArray = search.split('&');
            for (i in keypairArray) {
                keypair = keypairArray[i];
                partArray = keypair.split('=');
                if(partArray.length == 2){
                    obj[partArray[0]] = partArray[1];
                }
            }
        }
        return obj;
    }

console.dir(getParameters());
