復(fù)制代碼 代碼如下:
//公司二維數(shù)組數(shù)據(jù)源
Office = [
["Dept", "ParentDept"],
["業(yè)務(wù)部", "0"],
["技術(shù)部", "0"],
["市場(chǎng)部", "0"],
["www.yongfa365.com", "業(yè)務(wù)部"],
["業(yè)務(wù)部小楊", "業(yè)務(wù)部"],
["業(yè)務(wù)部小菜", "業(yè)務(wù)部"],
["技術(shù)部老柳", "技術(shù)部"],
["技術(shù)部老楊", "技術(shù)部"],
["技術(shù)部老菜", "技術(shù)部"],
["市場(chǎng)部柳先生", "市場(chǎng)部"],
["市場(chǎng)部楊先生", "市場(chǎng)部"],
["市場(chǎng)部菜鳥(niǎo)", "市場(chǎng)部"]
]
//省市三維數(shù)組數(shù)據(jù)源
City3 = [
["Dept", "ParentId", "Id"],
["北京", "0", "010"],
["山西", "0", "0359"],
["朝陽(yáng)區(qū)", "010", "001"],
["海淀區(qū)", "010", "002"],
["豆各莊", "001", "101"],
["十里堡", "001", "102"],
["中關(guān)村", "002", "201"],
["上地", "002", "202"],
["運(yùn)城地區(qū)", "0359", "301"],
["太原市", "0359", "302"],
["永濟(jì)市", "301", "311"],
["小區(qū)", "302", "312"]
];
//FillSelectTree("nowhaha", City3, "0", "311", -1)
//Select控件ID,數(shù)據(jù)源,父級(jí)值,選中值,第幾級(jí)（用來(lái)產(chǎn)生分隔符）
function FillSelectTree(SelectId, ArrObj, ParentValue, SelectedValue, NowI) {
StrObj = eval(document.getElementById(SelectId));
NowI++;
//判斷它是二級(jí)數(shù)據(jù)源，還是三級(jí)
if (ArrObj[0].length == 2)
{ ArrNum = 0; }
else
{ ArrNum = 2; }
//生成所有Option
for (var i = 0; i < ArrObj.length; i++) {
if (ArrObj[i][1] == ParentValue) {
StrObj.options[StrObj.length] = new Option(String(" ", NowI) + ArrObj[i][0], ArrObj[i][ArrNum]);
//選中默認(rèn)值
if (ArrObj[i][ArrNum] == SelectedValue) {
StrObj.options[StrObj.length - 1].selected = true;
}
//遍歷
FillSelectTree(SelectId, ArrObj, ArrObj[i][ArrNum], SelectedValue, NowI);
}
}
}
//復(fù)制字符串多少次
function String(str, nowi) {
strtemp = "";
for (var i = 0; i < nowi; i++) {
strtemp += str;
}
return strtemp;
}
