JQgrid編輯時給必填項加上提示

JQgrid在添加和編輯時，彈出的編輯框裏面，難免會很有一些默認必填的選項，但是這個插件我沒有在官網文檔裏面找到默認給這些項加必填提示的參數，只有在點擊提交的時候纔有參數校驗對必填項進行驗證提示。
所以我在源碼裏面做了一下修改，如下，位置在 editGridRow->callback for each()-> createData -> callback for each()裏面，具體如下圖

//判斷這個標籤是否是必填項，是的話在標籤上加入 * 標記
	var node =obj.p.colModel[i];
	var label = obj.p.colNames[i];
	if (typeof(node.editable) != "undefined" && node.editable
		&& typeof(node.editrules) != "undefined" && typeof(node.editrules.required) != "undefined"
		&& node.editrules.required )
		label = obj.p.colNames[i] + "*";
	$("td:eq("+(cp-2)+")",trdata[0]).html(frmopt.label === undefined ? label: frmopt.label);

效果圖如圖：

最後再將這個代碼所在的方法的完整代碼貼一下

function createData(rowid,obj,tb,maxcols){
				var nm, hc,trdata, cnt=0,tmp, dc,elc, retpos=[], ind=false,
				tdtmpl = "<td class='CaptionTD'>&#160;</td><td class='DataTD'>&#160;</td>", tmpl="", i; //*2
