js中回车触发事件
一、
document.onkeydown = function (e) { // 回车提交表单 // 兼容FF和IE和Opera var theEvent = window.event || e; var code = theEvent.keyCode || theEvent.which || theEvent.charCode; if (code == 13) { queryInfo(); } }
二、JS监听某个DIV区域
$("#queryTable").bind("keydown",function(e){ // 兼容FF和IE和Opera var theEvent = e || window.event; var code = theEvent.keyCode || theEvent.which || theEvent.charCode; if (code == 13) { //回车执行查询 $("#queryButton").click(); } });
三、JS监听某个输入框
//回车事件绑定 $('#search_input').bind('keyup', function(event) { if (event.keyCode == "13") { //回车执行查询 $('#search_button').click(); } });
js实现鼠标焦点自动落到文本框
window.onload = function(){ var oInput = document.getElementById("strName"); oInput.focus(); }
