How to use jQuery.param
This article mainly explains "how to use jQuery.param". Friends who are interested might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn how to use jQuery.param.
The input element is also a serialized element in jQuery 1.4 HTML5.
We can display a query string for an object and a corresponding URI-decoded version, as follows:
Var myObject = {
A: {
One: 1
Two: 2
Three: 3
}
B: [1,2,3]
}
Var recursiveEncoded = $.param (myObject)
Var recursiveDecoded = decodeURIComponent ($.param (myObject))
Alert (recursiveEncoded)
Alert (recursiveDecoded)
The results of recursiveEncoded and recursiveDecoded are as follows:
A%5Bone%5D=1&a%5Btwo%5D=2&a%5Bthree%5D=3&b%5B%5D=1&b%5B%5D=2&b%5B%5D=3
A [one] = 1 & a [two] = 2 & a [three] = 3 [] = 1 [] = 2 [] = 3
Before jQuery1.4, to mimic the behavior of $.param (), we can set the traditional parameter to true:
Var myObject = {
A: {
One: 1
Two: 2
Three: 3
}
B: [1,2,3]
}
Var shallowEncoded = $.param (myObject, true)
Var shallowDecoded = decodeURIComponent (shallowEncoded)
Alert (shallowEncoded)
Alert (shallowDecoded)
The results of shallowEncoded and shallowDecoded are as follows:
A=%5Bobject+Object%5D&b=1&b=2&b=3
A = [object + Object] & b=1&b=2&b=3
Example:
Example: serialize a key/value object. / span >
Div {color:red;}
Var params = {width:1680, height:1050}
Var str = jQuery.param (params)
$("# results") .text (str)
Demo:
Example: serial number of some complex objects
/ / = 1.4:
$.param ({a: [2helm 3jue 4]}) / / "a [] = 2yoga [] = 3beaua [] = 4"
/ / = 1.4:
$.param ({a: {bburet 1 magnificent cjoun 2}, d: [3pr 4, {evision 5}]}) / / "a [b] = 1 & a [c] = 2d [] = 3d [] = 4fud [2] [e] = 5"
