function changePic(strPath)
{
    alert(strPath);
    document.getElementById('ctl00_ContentPlaceHolderTM_imgAddPhoto').src=strPath;
}

推荐答案

此代码正确.

This code is correct.

document.getElementById(''ctl00_ContentPlaceHolderTM_imgAddPhoto'').src=strPath;

只要图像路径正确，这肯定会起作用，并且图像会相应显示.确保路径上存在图像.通常，这是因为形成了错误的相对路径.纠正它，它将起作用.

This would surely work and image would be displayed accordingly as long as the image path is correct. Make sure an image exists on the path. Mostly, it would be because of wrong relative path formed. Correct it and it would work.
