jsp回车事件

1、 JS监听body区域

document.onkeydown = function(e){
        var ev = document.all ? window.event : e;
        if(ev.keyCode==13) {
            //操作的业务逻辑
        }
    };

2、jq方式实现

    1）监听某个输入框

$("#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) {//操作的业务逻辑}    });    

    2) 监听某个div的区域

$("#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) {    
         //操作的业务逻辑}    });

3、onkeydown="enter(event)"方式实现

//回车事件执行方法
    function enter(event) {  
	  
	    var browser = navigator.appName;  
	    var userAgent = navigator.userAgent;  
	    var code;  
	    if(browser.indexOf('Internet')>-1) //IE  
	    code = window.event.keyCode;  
	    else if(userAgent.indexOf("Firefox")>-1)  //火狐  
	    code = event.which;  
	    else  //其它浏览器  
	    code = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;  
	    if ( code == 13){
	    	//操作的业务逻辑
	    }
	        
	}
