JS獲取地址欄參數的幾種方法小結

複製代碼代碼如下:

<script>

// 獲取地址欄的參數數組

function getUrlParams() {

var search = window.location.search;

// 寫入數據字典

var tmparray = search.substr(1, search.length).split("&");

var paramsArray = new Array;

if (tmparray != null) {

for (var i = 0; i < tmparray.length; i++) {

var reg = /[=|^==]/; // 用=進行拆分，但不包括==

var set1 = tmparray[i].replace(reg, '&');

var tmpStr2 = set1.split('&');

var array = new Array;

array[tmpStr2[0]] = tmpStr2[1];

paramsArray.push(array);

}

}

// 將參數數組進行返回

return paramsArray;

}

// 根據參數名稱獲取參數值

function getParamValue(name) {

var paramsArray = getUrlParams();

if (paramsArray != null) {

for (var i = 0; i < paramsArray.length; i++) {

for (var j in paramsArray[i]) {

if (j == name) {

return paramsArray[i][j];

}

}

}

}

return null;

}

function test()

{

alert("v="+getParamValue("name"));

}

var test1= function()

{

//alert("v1="+getParamValue("name"));

//alert("v2="+GetUrlParam("name"));

//alert("v3="+GetUrlParms("name"));

alert("v4="+getQuery("name"));

}

function GetUrlParam(paramName) {

var url = document.URL; //URL參數，你也可以用document.URL來獲取，方法太多了

var oRegex = new RegExp('[/?&]' + paramName + '=([^&]+)', 'i');

//var oMatch = oRegex.exec( window.top.location.search ) ; //獲取當前窗口的URL

var oMatch = oRegex.exec(url);

if (oMatch && oMatch.length > 1)

return oMatch[1]; //返回值

else

return '';

}

//獲取url參數

function GetUrlParms(name) {

var reg = new RegExp("(^|//?|&)" + name + "=([^&]*)(//s|&|$)", "i");

if (reg.test(location.href))

return unescape(RegExp.$2.replace(//+/g, " "));

return "";

}

var getQuery = function (i) {

var j = location.search.match(new RegExp("[?&]" + i + "=([^&]*)(&?)", "i"));

return j ? j[1] : j

};

</script>
