html代码：
<select name="ruleId" id="ruleId" class="required" onchange="selectRule()" multiple="multiple" class="form-control">
<c:forEach items="${fns:selectRuleListBycompany()}" var="item">
<option value="${item.id}"
<c:if test="${record.ruleId == item.id}">
selected="selected"
</c:if>>${item.ruleName}
</option>
</c:forEach>
</select>
js获取全部的值并放入到数组中
window.Garray = new Array(); //定义窗口全局变量数组
function selectRule(obj){
var selected = $("#ruleId").select2('data');
window.Garray = [];
for (var i = 0; i < selected.length; i++) {
Garray.push(selected[i].id);
}
}
$(function(){
var arrs = new Array();
var str = "${record.ruleIdList}";
arrs = str.replace('[','').replace(']','').replace(/\s/g,'').split(',');
$("#ruleId").val(arrs).trigger("change");
});
