JSはURL_javascriptスキルでパラメータデータを取得します

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 if (arrSource[i].indexOf("=") > 0) {
if (arrSource[i].split("=")[0].toLowerCase() == paramName.toLowerCase()) {
paramValue = arrSource[i].split("=")[1];
isFound = true;
}
}
私 ;
}
}
return paramValue;
}
