JS鼠标双击事件 onDblClick
< td width = " 10% " title = " 双击修改 " ondblclick = " ShowElement(this,<%#Eval( " id " ) %> </ td >
这里的本人用绑定的值是传的当前行对应的ID号,
function ShowElement(element, productid, flag, ishotorcommend) { if (flag == 0 && ishotorcommend == 0 ) { alert( " 请先设置该产品为推荐 " ); return ; } if (flag == 1 && ishotorcommend == 0 ) { alert( " 请先设置该产品为热销 " ); return ; } var oldhtml = element.innerHTML; // 原单元格里的值 var str = " <input type='text' name='test' style='width:50%;' " ; str += " οnkeypress='return event.keyCode>=48&&event.keyCode<=57||event.keyCode==46' " ; str += " οnpaste='return !clipboardData.getData('text').match(/\D/)' " ; str += " οndragenter='return false' /> " ; var newobj = document.createElement(str); // 创建新的input元素 newobj.setAttribute( " value " , oldhtml); // 把原来单元格中的值赋给文本框 newobj.onblur = function () { element.innerHTML = this .value ? this .value : oldhtml; // 当触发时判断新增元素值是否为空,为空则不修改,并返回原有值 var sort = element.innerHTML; $.get( " UpdateFlag.ashx?sort= " + sort + " &&productid= " + productid + " &&flag= " + flag, function (data) { }); } element.innerHTML = '' ; element.appendChild(newobj); // 把新的值赋到单元格 newobj.focus();}
