鼠标悬停改变颜色

Question

I'ld like to change the " imgTag.style.border='5px solid #FF00FF' " to black when the mouse is over an image. This is my JavaScript:

javascript:for(i=0;i<document.getElementsByTagName('img').length;i++)  
     {
     var imgTag=document.getElementsByTagName('img')[i];   
     imgTag.style.border='5px solid #FF00FF';
     imgTag.title=''; 
     imgTag.onclick=function()
          { 
         return !window.open('http://www.example.com/#/'+this.src);
          }
      }
    void(0)

How can it be done? Thanks Frank

You need to bind handlers to the mouseover and mouseout events to change the image's border color:

var imgs = document.getElementsByTagName('img');
for(var i = 0; i < imgs.length; ++i) {
    imgs[i].onmouseover = function() {
        this.style.borderColor = '#000';
    };
    imgs[i].onmouseout = function() {
        this.style.borderColor = '#f0f';
    };
}

Not sure what's wrong with the code you have, but if i understand your question correctly, this should do it: HTML:

<img src="" >
<img src="">
...

JS:

var imgs = document.getElementsByTagName("img");
for(i=0;i<imgs.length;i++)
{
    imgs[i].onmouseover = function() {this.style.border="1px red solid";};   
}

Note, however, that this can easily be achieved with CSS as well, which is a better practice - in case users have JS disabled, etc

img:hover {
border: 1px red solid;
}
