Methods for breaking up content client-side into multiple "pages"
I have a long HTML text-only article formatted with paragraph tags. What I'd 开发者_Go百科like to do is break this content into N number of divs so that I can create individual pages. So, for instance, on an iPad/iPhone, instead of reading one long page the user could swipe right/left to navigate to pages.
My initial javascript attempts have been somewhat convoluted: creating an array of the text, measuring line-heights, device window heights, adding closing/opening paragraph tags and the end/beginning of pages.
Thoughts on a good way to approach this? I will not have access to server-side processing, this has to be a client-side solution.
How about a div that scrolls a fixed amount on the click of a button?
I've used YUI here, but it's easily translatable. Basically you just create a fixed size div and change it's scrollTop value on click.
<html><head><script type="text/javascript" src="http://yui.yahooapis.com/combo?2.8.1/build/yahoo-dom-event/yahoo-dom-event.js"></script>
<style>
#page {
border: inset;
height:400px;
width:400px;
overflow:hidden;
}
</style>
<script>
(function() {
var Dom = YAHOO.util.Dom,
Evt = YAHOO.util.Event;
var getPageSize = function(){
return Dom.get('size').value;
};
Evt.addListener('Next', "click", function() {
var page = document.getElementById('page');
Dom.get('page').scrollTop += getPageSize();
});
Evt.addListener('Previous', "click", function() {
var page = document.getElementById('page');
Dom.get('page').scrollTop -= getPageSize();
});
})();
</script></head>
<body><input type='text' id='size' value='50'>
<div id='Next'>Next</div>
<div id='Previous'>Previous</div>
<div id='page'> INSERT LOTS OF TEXT HERE </div></body></html>
