This article introduces the relevant knowledge of "getScript cache response case analysis". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Caching Responses (cached response)

By default, the $.getScript () cache option is set to false. This appends a timestamp parameter to the query string of the requested URL to ensure that each script downloaded by the browser is re-requested. You can override this feature globally with the $.ajaxSetup () setting cache (cache) property:

$.ajaxSetup ({

Cache: true

})

In addition, you can define a new method using the more flexible $.ajax () method

Example:

Example: defines a script where the $.cachedScript () method can get the cache:

JQuery.cachedScript = function (url, options) {

/ / allow user to set any option except for dataType, cache, and url

Options = $.extend (options | | {}, {

DataType: "script"

Cache: true

Url: url

})

/ / Use $.ajax () since it is more flexible than $.getScript

/ / Return the jqXHR object so we can chain callbacks

Return jQuery.ajax (options)

}

/ / Usage

$.cachedScript ("ajax/test.js") .done (function (script, textStatus) {

Console.log (textStatus)

})

Example: we dynamically load the new official jQuery color animation plug-in, which will trigger some color animation once the plug-in is loaded.

.block {

Background-color: blue

Width: 150px

Height: 70px

Margin: 10px

}

»Run

(function () {

Var url = "https://raw.github.com/jquery/jquery-color/master/jquery.color.js";

$.getScript (url, function () {

$("# go") .click (function () {

$(".block")

.animate ({backgroundColor: "rgb (255,180,180)"}, 1000)

.delay (500)

.animate ({backgroundColor: "olive"}, 1000)

.delay (500)

.animate ({backgroundColor: "# 00f"}, 1000)

})

})

) ()
