What is the process of rolling the pulley to the bottom of the page to load data with ajax and jsonp
This issue of the content of the editor will bring you about the pulley scrolling to the bottom of the page ajax loading data with jsonp implementation process is how, the article is rich in content and professional analysis and description for you, after reading this article, I hope you can get something.
Scrolling down to the bottom of the page to load data is the practice of many waterfall streaming sites, so let's take a look at how to cooperate with jsonp.
Of course, this example uses the jquery library, which will be made into native js later.
The data in this example invokes a json provided by the sharp jquery book.
The first step is to determine how the page scrolls to the bottom, that is, whether the height of scrollTop+window is greater than the height,jquery of document. The code is as follows: $(window). ScrollTop () + $(window). Height () > = $(document). Height ()
Then bind the scroll event to window. So the entire page demo can do this:
The code is as follows:
* {margin:0; padding:0;}
Body {font-size:12px;}
P {margin: 5px;}
.box {padding: 10px;}
$(function () {)
$(window) .bind ('scroll',function () {show ()})
Function show ()
{
If ($(window) .scrollTop () + $(window) .height () > = $(document) .height ())
{
AjaxRead ()
}
}
Function ajaxRead ()
{
Var html= ""
$.ajax ({
Type:'get'
DataType:'jsonp'
Url:' http://api.flickr.com/services/feeds/photos_public.gne?tags=car&tagmode=any&format=json&jsoncallback=?',
BeforeSend:function () {console.log ('loading...')}
Success:function (data) {
$.each (data.items,function (ither item) {
Html+=''
Html+=''+item.title+''
Html+='
'
Html+=''+item.tags+''
Html+=''
});
("# resText") .append ($(html))
}
Complete:function () {console.log ('mission acomplete.')}
});
}
})
