今天在做网站进,要求一个指定的效果。点击了图片后,在原来图片上放大显示一个图片,一看,那效果还不错,所以就收藏了。

下面是JS代码:

var hs = {

// Apply your own settings here, or override them in the html file. 
graphicsDir : 'highslide/graphics/',
restoreCursor : "zoomout.cur", // necessary for preload
expandSteps : 10, // number of steps in zoom. Each step lasts for duration/step milliseconds.
expandDuration : 250, // milliseconds
restoreSteps : 10,
restoreDuration : 250,
allowMultipleInstances: true,
hideThumbOnExpand : true,
captionSlideSpeed : 1, // set to 0 to disable slide in effect
outlineWhileAnimating : false, // not recommended, animation gets jaggy on slow systems.
outlineStartOffset : 3, // ends at 10
marginLeft : 10,
marginRight : 35, // leave room for scrollbars + outline
marginTop : 10,
marginBottom : 35, // leave room for scrollbars + outline
numberOfImagesToPreload : 5,
zIndexCounter : 1001, // adjust to other absolutely positioned elements
fullExpandIcon : 'fullexpand.gif',
fullExpandTitle : 'Expand to actual size',
restoreTitle : '',
focusTitle : 'Click to bring to front',
loadingText : 'Loading...',
loadingTitle : 'Click to cancel',
loadingOpacity : 0.75,
showCredits : true, // you can set this to false if you want
creditsText : '',
creditsHref : '',
creditsTitle : '',
enableKeyListener : true,

// These settings can also be overridden inline for each image
anchor : 'auto', // where the image expands from
align : 'auto', // position in the client (overrides anchor)
targetX: null, // the id of a target element
targetY: null,
captionId : null,
captionTemplateId : null,
slideshowGroup : null, // defines groups for next/previous links and keystrokes
spaceForCaption : 30, // leaves space below images with captions
minWidth: 200,
minHeight: 200,
allowSizeReduction: true, // allow the image to reduce to fit client size. If false, this overrides minWidth and minHeight
outlineType : 'drop-shadow', // set null to disable outlines
wrapperClassName : null, // for enhanced css-control

  
// END OF YOUR SETTINGS

将上面代码生成一个JS文件,调用过来就可以了。

下面是在网页里调用的方法:

调用JS
<script type="text/javascript" src="bigimg.js"></script>
<script type="text/javascript">   
    hs.graphicsDir = '/';
    hs.outlineType = '';
</script>
<script language="javascript">
function $(objName){
 return document.getElementById(objName);
}

function showAndHidden(show){
 if($(show).style.display == "none"){
  $(show).style.display = "";
 }else{
  $(show).style.display = "none";
 }
}
</script>

在图片调用
<a href="BigimgPage.jpg" onclick="return hs.expand(this, {captionId: 'caption1'})"><img src="imgPage.jpg" width="213" height="170" vspace="10" border="0" ></a>

就这样Ok了。呵呵。

上一条:iframe父级表单的赋值与获得
下一条:JS随机产生一段字符串
