dojo小例子(28)FilteringSelect设置了queryExpr后无法弹出下拉项

FilteringSelect在html文件中能显示下拉项,但放在jsp文件中就无法弹出。FilteringSelect的创建代码如下:

var mem = new Memory({
	idProperty:"key",
	data:[
		{key:"6",name:"jut1"},
		{key:"7",name:"jut2"},
		{key:"8",name:"jut3"},
		{key:"9",name:"jut4"},
		{key:"5",name:"jut5"}
	]
});
var s = new FilteringSelect ({
	placeHolder : "请输入名称",
	required : false,
	disabled : false,
	store: mem,
	queryExpr : "*${0}*",
	labelType : "text",
	autoComplete : false,
	autoWidth : true,
	highlightMatch : "all",
	searchAttr: "name",
	style: {width: "180px"}
},"div_edit");
s.startup();

观察jsp页面的FilteringSelect加载后,在Firefox下输出queryExpr属性值,该值发生了改变,*${0}*变成了*0*;而html页面的queryExpr属性值没发生改变。原来是由于jsp会自动解析EL表达式,而dojo的*${0}*用法符合EL语法,从而被错误解析。解决办法,就是禁止EL表达式解析:

<%@page isELIgnored="true" %>
