js_javascript スキルで重複した文字列を削除する 2 つの方法

方法一：

复制代码代码如下:

function checkRe( checkid) {

var id = window.parent.getQry("ctrid") "_";

var 値 = window.parent.opener.document.getElementById(id "txt_dept_name").value;
var key = window.parent.opener.document.getElementById(id "hf_ids").value;

var ary = checkid.value.split("|");
var newsValues = ary[0];
var newsKeys = ary[1];

if (checkid.checked) {
values = 値 "," newsValues;
keys = キー "," newsKeys;

}
else {
values = value.replace(new RegExp("," newsValues), "");
keys = value.replace(new RegExp("," newsKeys), "");

}

値 = okd(値);
キー = okd(キー);

window.parent.opener.document.getElementById(id "txt_dept_name").value = 値;
window.parent.opener.document.getElementById(id "hf_ids").value = キー;

戻る;

}
//数値グループを変換し、繰り返し、再結合します。
function okd(str) {

var ary = str.split(",");
//去重的算法
var json = {};
for (var i = 0; i < ary.length; i ) {

if (ary[i] != "") {

json["a" ary [i]] = ary[i];
}
}

// 查看結果
var str2 = "";
for (json の var key) {
str2 = "," json[key];
}

var s = str2.toString();

//去掉第一个逗号
if (s.substr(0, 1) == ',') {
s = s.substr(1);
}

s を返します。
}

function add_all() {
var ck = document.getElementsByTagName("input");
for (i = 0; i if (ck[i].type == "checkbox") {
ck[i].checked = true;
checkRe(ck[i]);

}
}

}

function del_all() {
var id = window.parent.getQry("ctrid") "_";
window.parent.opener.document.getElementById(id "txt_dept_name").value = "";
window.parent.opener.document.getElementById(id "hf_ids").value = "";

var ck = document.getElementsByTagName("input");
for (i = 0; i if (ck[i].type == "checkbox") {
ck[i].checked = false;

}
}
}

复制代 代価次のように:

方法二：

复制代代码如下:

function filterRepeatStr(str){
var ar2 = str.split(",");
var array = new Array();
var j=0
for(var i=0;iif((array == "" || array.toString().match(new RegExp( ar2[i],"g")) == null)&&ar2[i]!=""){
array[j] =ar2[i];
array.sort();
j ;
}
}
return array.toString();
}
