**JS 监听输入框按键**

//回车事件绑定
    $('#search_input').bind('keyup', function(event) {
        if (event.keyCode == '13') {
            //处理按回车键后的逻辑
            
        }
    });

**JS 监听某个 DIV 区域**

$("#div").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') {    
            //处理按回车键后的逻辑
            
        }    
    });

**JS监听body区域**

document.onkeydown = function (event) {
        var e = event || window.event;
        if (e && e.keyCode == 13) {
            //处理按回车键后的逻辑
        }
    }
