Today, the editor will share with you the relevant knowledge points about how to achieve lazy loading in jquery. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

To introduce two files, note that these things are contained in the html

Then configure what you need under query.lazyload.js.

$(function () {)

$("img.lazy") Lazyload ({

Placeholder: ",? / / the placeholder displayed when the picture is not loaded.

Effect: "show",? / / presentation method, commonly used: show display\ fadeIn flash

Threshold:100,? / / starts loading at how many px away from the screen

Event: "scroll",? / / trigger event of lazy loading. Commonly used: click click / mouseover mouse move / sporty movement / default is scroll slide

Container:$ ("# J-sourceList"), / / specify the elements in the container to produce an effect

Failure_limit:5? / / load how many pictures outside the visible area

})

})

Then it is suggested that the size of the img should be uniform as far as possible, so it is perfect to write a class directly, because I find that I need to configure the img. If width height is not given, it may not be loaded.
