DWZ 查询检索时解决 pageNum,numPerPage,orderField,orderDirection信息丢失问题

　　检索时如果先更改了numPerPage，检索会出现numPerPage信息丢失，回到默认值，排序字段orderField、orderDirection信息也将丢失

　　解决办法：修改js/dwz.ajax.js中两个方法　navTabSearch，　dialogSearch

　　如果使用了bin/dwz.min.js也是修改两个方法　navTabSearch，　dialogSearch

/**
 * 处理navTab上的查询, 会重新载入当前navTab
 * @param {Object} form

function navTabSearch(form, navTabId){
	var $form = $(form);
	if (form[DWZ.pageInfo.pageNum]) form[DWZ.pageInfo.pageNum].value = 1;
	/*add by mengx begin*/
	var args_form = $form.size()>0 ? $form.serializeArray() : {};
	var $pagerForm = $("#pagerForm", navTab.getCurrentPanel());
	var args_pagerForm = $pagerForm.size()>0 ? $pagerForm.serializeArray() : {};
	for(var i in args_form){
		for(var j in args_pagerForm){
			if(args_pagerForm[j].name == args_form[i].name){
				args_pagerForm[j].value = args_form[i].value;
				break;
			}
		}
	}
	navTab.reload($form.attr('action'), {data: args_pagerForm, navTabId:navTabId});
	/*add by mengx end*/
	//$.pdialog.reload($form.attr('action'), {data: $form.serializeArray()});
	return false;
}
