Javascript JQuery：如何禁用鼠标垂直移动？

我正在使用鼠标单击事件创建元素选择器链接。您可以单击一个单元格并根据需要进行拖动（将显示绿色）。 我的问题是如何禁用鼠标在单击和拖动时垂直移动？用户只能水平拖动。下面是我的代码

HTML

<div id="grid">
                <div class="gridHeader">
                    <span><label>#</label></span>
                        <span><label>01</label></span>

脚本

$(document).ready(function(){
    $('#grid .item').mousedown(function(){
        $(this).attr("style", "background-color:green");
        $('#grid .item').mouseenter(function(){
            $(this).attr("style", "background-color:green");
        });
    });
    $('#grid .item').mouseup(function(){
        $('#grid .item').unbind('mouseenter');
    });
});

您不需要阻止垂直鼠标移动。您只需捕获适当的元素及其同级，并将每个事件附加到放置项的类，如下所示：

$(document).ready(function(){
        $('.gridRow .item').mousedown(function(){
            $(this).attr("style", "background-color:green");
            $(this).siblings().mouseenter(function(){ 
            //^^^^style only its siblings where mouse has been clicked
                $(this).attr("style", "background-color:green");
        });
    });
});

仅供参考，您不能限制鼠标的实际运动。如果用户想离开你的窗口，他们可以。您可以限制鼠标左/右移动时发生的情况，并忽略垂直运动。您必须以不同的方式实现命中检测，以便只响应开始拖动的行中的项目。噢！你说得对。谢谢你，先生<代码>$（this）.sibbines（）非常有用。但我需要在鼠标被释放时解除绑定事件，并且不应该应用列（房间xxx）（我想我可以处理这个）。谢谢。@Cataclysm。。随时快乐编码！！如果您遇到任何问题，请告知！！供您参考，可能会对您有所帮助！！

$(document).ready(function(){
        $('.gridRow .item').mousedown(function(){
            $(this).attr("style", "background-color:green");
            $(this).siblings().mouseenter(function(){ 
            //^^^^style only its siblings where mouse has been clicked
                $(this).attr("style", "background-color:green");
        });
    });
});
