复制代码 代码如下:

function getParam(paramName) {

paramValue = "";

isFound = false;

if (this.location.search.indexOf("?") == 0 && this.location.search.indexOf("=") > 1) {

arrSource = unescape(this.location.search).substring(1, this.location.search.length).split("&");

i = 0;

while (i < arrSource.length && !isFound) {

if (arrSource[i].indexOf("=") > 0) {

if (arrSource[i].split("=")[0].toLowerCase() == paramName.toLowerCase()) {

paramValue = arrSource[i].split("=")[1];

isFound = true;

}

}

i++;

}

}

return paramValue;

}

getParam("id")为202
