通過(guò)數(shù)值對(duì)應(yīng)給checkbox的設(shè)置默認(rèn)屬性值（勾選狀態(tài)）

//初始化默認(rèn)已擁有的權(quán)限$(function () { /*  獲取所有復(fù)選框的值    var box = document.getElementsByName("user-Character-0-0-0"); var objArray = box.length; var chestr=""; for(var i=0;i<objArray;i++){  chestr+=box[i].value+","; } alert(chestr);*/ var roleName = $("#roleName").val();//獲取需要初始化的數(shù)值 //把已經(jīng)擁有的復(fù)選框的屬性值變成true var arrStr = roleName.split(",");//轉(zhuǎn)化成數(shù)組 for (var i = 0; i < arrStr.length; i++) { $("input[Value=" + arrStr[i] + "]").attr("checked", "checked");//根據(jù)value給checkbox設(shè)置默認(rèn)值（勾選） }});
