方法一：

复制代码 代码如下:

function checkRe(checkid) {

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

var values = window.parent.opener.document.getElementById(id + "txt_dept_name").value;

var keys = 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 = values + "," + newsValues;

keys = keys + "," + newsKeys;

}

else {

values = values.replace(new RegExp("," + newsValues), "");

keys = values.replace(new RegExp("," + newsKeys), "");

}

values = okd(values);

keys = okd(keys);

window.parent.opener.document.getElementById(id + "txt_dept_name").value = values;

window.parent.opener.document.getElementById(id + "hf_ids").value = keys;

return;

}

//转换成数组，去掉重复，再组合好。

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];

}

}

// 查看结果

var str2 = "";

for (var key in json) {

str2 += "," + json[key];

}

var s = str2.toString();

//去掉第一个逗号

if (s.substr(0, 1) == ',') {

s = s.substr(1);

}

return s;

}

function add_all() {

var ck = document.getElementsByTagName("input");

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

if (ck[i].type == "checkbox") {

ck[i].checked = false;

}

}

}

 

复制代码 代码如下:

<input id='chk_pkId' type='checkbox' name='chk' οnclick='checkRe(this);' value='值|pkId' />

方法二：

复制代码 代码如下:

function filterRepeatStr(str){

var ar2 = str.split(",");

var array = new Array();

var j=0

for(var i=0;i<ar2.length;i++){

if((array == "" || array.toString().match(new RegExp(ar2[i],"g")) == null)&&ar2[i]!=""){

array[j] =ar2[i];

array.sort();

j++;

}

}

return array.toString();

}
