动态创建table,按回车键自动切换光标位置及金额统计Js代码实现
1.JS页面输出拼接的Table代码,参数来自于Ajax请求响应回来的Json数据
$("#rightTipPayBackTb").append("<tr><td>" + successCount + "</td><td>" + datas.Data.WayBillCode + "</td><td><input type=\"text\" onkeydown='if(event.keyCode==13)Alt.nextFocus(this);' onKeypress='Alt.only_number()' onfocus='this.select()' onKeyUp='Alt.text_zero(this);Alt.TipPayBack.getTotal()' id=\"txt" + datas.Data.WayBillCode + "\" name=\"tipAmount\" value='" + datas.Data.TipAmount + "' /></td><td>" + datas.Data.QuidcoDirectoryName + "</td><td style='color:blue;' onclick='Alt.TipPayBack.removeTipPayBack(this)'>删除</td></tr>");
2.Function函数,altBase作为全局调用封装的js代码
- getTotal() 金额合计,根据实际业务代码自己编写;
-
//增加按回车键实现代码
altBase.only_number = function () {
if (event.keyCode < 45 || event.keyCode > 57) event.returnValue = false;
} -
//控件为空则为0 chenww 2017-10-23
altBase.text_zero = function (text) {
if (text.value == '') {
text.value = 0
text.select();
}
} -
//下移光标
altBase.nextFocus = function (the) {
var oo = document.getElementsByName(the.name);
var isFocus = false;
for (i = 0; i < oo.length; i++) {
if (isFocus) {
oo[i].focus();
break;
}
if (oo[i] == the) {
isFocus = true;
}
}
}
3.总结:以上是实现的核心的js代码,仅供参考;
