JS把url的参数解析成对象

// url参数解析
function getUrlkey(url) {
 var params = {};
 var urls = url.split("?"); console.log('1_分割url:', urls)
 var arr = urls[1].split("&"); console.log('2_分割urls[1]:', arr)
 for (var i = 0, l = arr.length; i < l; i++) {
 var a = arr[i].split("="); console.log('3_遍历 arr 并分割后赋值给a:', a[0], a[1])
 params[a[0]] = a[1]; console.log('4_a给params对象赋值:', params)
 } console.log('5_结果:', params)
 return params;
}
