                                            单价
                                        
                                        
                                            总价
                                        
                                    
                                    
                                        
                                            
                                        
                                        
                                            
                                        
                                        
                                            
                                        
                                        
                                            
                                        
                                        
                                            
                                        
                                    
                                
                            
                        
                                                                                                                                                                       合计金额                                                                                                         

  示例中的子表最后一列为合计列,每一列其合计=单价*数量,金额总计=各行合计之和;

ueditor子表控件绑定事件的扩展优化

  js代码如下:

	function bindTableChange(){
		  $("input[name='s:cpxx:cpsl']," +
				"input[name='s:cpxx:cpdj']").bind('click change blur', function(){
					//计算金额事件
					calcSubTableMoney(this);
			});
		 
	}
	
	function calcSubTableMoney(self){
		  var blocktable = $(self).parent().parent().parent();
		    
		  var itdj = $.trim($("input[name='s:cpxx:cpdj']", $(blocktable)).val());//IT单价
		  var sl = $.trim($("input[name='s:cpxx:cpsl']", $(blocktable)).val());//数量
		  if($.isNumeric(itdj)&&$.isNumeric(sl)){
		    var dxhj=itdj*sl;
		    dxhj=parseFloat(dxhj).toFixed(2);
		     $("input[name='s:cpxx:cpzj']", $(blocktable)).val(dxhj);
		   sumHj();
		   }
		}

		//汇总合计
		function sumHj(){
		  var zhj=0;
		  var dxhjArray= document.getElementsByName("s:cpxx:cpzj");
		  for(var i=0;i
  1. 为单价和数量两个input均添加chang\blur\click事件,事件触发后会更新合计和总计值;

  2. $后有两个参数,第一个为操作对象,第二个定义操作对象所在的范围;由html可以看出单价或数量的parent.parent.parent即为tr,这样就限定了按行计算;

  3. parseFloat和toFixed为js的两个函数,分别为转换为float和四舍五入小数点后两位;

  4. isNumeric和trim为jQuery的两个函数,分别为判断是否为数字和去掉空格;

二、扩展和优化

  由于子表控件支持点击添加行,而在点击添加后由于新增的input并未注册事件,故无法使用算数计算合计和总计。我们采用一种为子表”添加“按钮添加exefunc,为新增行input增加注册事件,代码如下

function bindExtFunction(){
	$(".toolBar").attr("extfunc", "toolbarExtFunction");
}

/** 工具条扩展方法 */
function toolbarExtFunction(){
	//子表序列号
  //calcTableSerino();
	//子表下拉框、输入框事件绑定
	bindTableChange();
}

   toolBar为添加按钮的父对象,根据JQuery的传播机制,事件的注册会以捕获机制由父及子,再以冒泡机制以子及父,所以点击添加按钮后,会先运行父对象的相应函数,添加按钮后,会再次运行父对象从而为新增行注册事件。
