We may sometimes need to modify the information in the form. At this point, we need to use the UPDATE command. The syntax for this instruction is:UPDATE "Table name"SET "Field 1" = [New value]WHERE "condition";The easiest way to understand this syntax is through an example. Suppose we have the following table:store_information Form
Store_name
Sales
Txn_date

$. Extend ($. net, {hello: function () {alert ('hello') ;}}) This is to extend the hello Method to the expanded Jquery net namespace.
III. The extend method of Jquery also has an overload prototype:
Extend (boolean, dest, src1, src2, src3 ...)
The first parameter 'boolean' indicates whether to perform a deep copy. The other parameters are the same as described above. What is "Deep copy"? Let's look at an example:
Var result = $. extend (true, {}, {name: "John", location: {city: "
Do PHP inevitably touch js, I also like this, when using AJAX, I am more accustomed to using $.ajax ({}), this way, because of the strong general. Sometimes less use JS, after a period of time to use, some of the details are easy to obscure, this time, I forgot more parameters when the format of the data, so Baidu search, found:jquery手册描述:data sent to the server. is automatically converted to the request string format.

Now, I understand. If it is json data, we can concatenate strings using their name attribute and value Attribute in one loop.
For a common object, loop through the attributes of the object and splice the string.
Summary:
Therefore, in this article, three types of data can be imported into the ajax function of jquery.
1. Text: "uname = alice mobileept = 110 birthday ="
