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();
}
