Problem with JS dynamically setting image src address under IE6_javascript skills

I have been working on a project for the past two days, which required the mouse to click on the small picture to display the large picture, so I used JS to set the SRC of the large picture based on the small picture. After the design was completed, the problem came out. The large image cannot be displayed under IE6. The link address can be displayed normally when the mouse is placed on the image and right-clicked. Only by clicking Show Image can the image be displayed normally. IE7, IE8 and FF do not have these problems. The code is as follows:

Copy code The code is as follows:

function picclick()
{
var pic = $('marqueediv').getElementsByTagName('a');
var len = pic.length;
for(var i = 0; i {
pic[i].onclick = function(i)
{
return function()
{
for(var t = 0; t {
pic[t].className = t == i ? 'hover' : '';
this.className = 'hover'
}
var thispic;
sspic = pic[i ].childNodes[0].src;
thispic = 'uploadimg/' sspic.substring(sspic.indexOf('uploadimg/s'), sspic.length).replace('uploadimg/s', '');
$('pro_pic_item').setAttribute('src', thispic);
$('pro_pic_item').setAttribute('alt', 'images');
//Solution: here Add "return false;"
return false;
}
}
(i)
}
}

According to the Internet, this It is due to a problem with the underlying judgment discontinuity factor under IE6.
