<div class="row cl"> <label class="form-label col-xs-4 col-sm-2">图片</label> <div class="formControls col-xs-8 col-sm-9"> <script type="text/javascript" src="js/selimage.js"></script> <input class="image" type="text" name="image" id="image" onclick="selimage('image');" placeholder="请选择图片" readonly="readonly" /> </div> </div> <div class="row cl"> <label class="form-label col-xs-4 col-sm-2">详情页图</label> <div class="formControls col-xs-8 col-sm-9"> <script type="text/javascript" src="js/selimage.js"></script> <input class="image" type="text" name="image1" id="image1" onclick="selimage('image1');" placeholder="请选择图片" readonly="readonly" /> </div> </div>两个input标签都同时使用selimage脚本，selimage脚本代码如下：function selimage() { window .open( "upload/preUpload.action", "", "toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=yes,copyhistory=no,scrollbars=yes,width=400,height=240,top=" + (screen.availHeight - 240) / 2 + ",left=" + (screen.availWidth - 400) / 2 + ""); } function savefile() { window .open( "upload/preFiles.action", "", "toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=yes,copyhistory=no,scrollbars=yes,width=400,height=240,top=" + (screen.availHeight - 240) / 2 + ",left=" + (screen.availWidth - 400) / 2 + ""); } 在上传图片时，第二张图会覆盖第一张图的文本框，该如何更改代码

你可以在selimage函数中传入一个参数，用来指定具体是哪个input标签被点击触发了该函数，然后分别给两个input标签指定不同的id和name，以避免覆盖。修改后的代码如下：

function selimage(inputName) { 
    window.open(
        "upload/preUpload.action",
        "",
        "toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=yes,copyhistory=no,scrollbars=yes,width=400,height=240,top="
        + (screen.availHeight - 240) / 2
        + ",left="
        + (screen.availWidth - 400) / 2 + ""
    );
    // 根据传入的参数设置对应的input标签
    document.getElementById(inputName).setAttribute('name', inputName);
    document.getElementById(inputName).setAttribute('id', inputName);
}

同时，你需要在HTML中将两个input标签的onclick事件分别指定为`selimage('image')`和`selimage('image1')`，并分别指定不同的id和name，如下所示：

<div class="row cl">
    <label class="form-label col-xs-4 col-sm-2">图片</label>
    <div class="formControls col-xs-8 col-sm-9">
        <script type="text/javascript" src="js/selimage.js"></script>
        <input class="image" type="text" name="image" id="image" onclick="selimage('image');" placeholder="请选择图片" readonly="readonly" />
    </div>
</div>
<div class="row cl">
    <label class="form-label col-xs-4 col-sm-2">详情页图</label>
    <div class="formControls col-xs-8 col-sm-9">
        <script type="text/javascript" src="js/selimage.js"></script>
        <input class="image" type="text" name="image1" id="image1" onclick="selimage('image1');" placeholder="请选择图片" readonly="readonly" />
    </div>
</div>
