Case Analysis of getScript Cache response
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)
})
})
) ()
