		url: "/chongwu_skill_category/selectAll",
		valueField: "id",
		textField: "name",
		width: 300,
		hasDownArrow: true,
		groupField: "type",
		panelHeight: "auto",
		prompt: "--请选择技能--",
		groupFormatter: function(group){
	        return "<span class='red'>" + skillTypes[group] + "</span>";
	    },
		formatter: function(row) {
			return "<img width='18' src='" + row.image + "' />&nbsp;" + row.name;
		}
	});

    $("#search").linkbutton({
		iconCls: "icon-search"
	}).click(function() {
		let categoryId = $("#category_id").combobox("getValue");
		let roleId = $("#role_id").combobox("getValue");
		let skillIds = $("#skill_ids").tagbox("getValues");
		$("#chongwu_list").datagrid("load", {
			roleId: roleId,
			skillIds: skillIds,
			categoryId: categoryId
		});
