Jquery uses Ajax to submit Form

Today, we can see how Jquery ajax submits data to the server. The original Article is:

Save the data to the server. If the data is successfully saved, the information is displayed.

JQuery code:
$. Ajax ({
Type: "POST ",
Url: "some. php ",
Data: "name = John & location = Boston ",
Success: function (msg ){
Alert ("Data Saved:" + msg );
}
}). I thought about it later. Is there any way to submit the form? However, I cannot write var demo =$ ("# divname"). val (); for every fom input.
Later, today I saw a method called. map, which I thought about and could be used for reference;
The html code is as follows. Next I want to submit all input data whose id is dlg_form,
<Form id = "dlg_form" method = "post">
<Div class = "fitem">
<Label> room: </label>
<Input name = "RoomName" style = "padding: 2px; width: 135px; border: 1px solid # A4BED4;" required/>
</Div>
<Div class = "fitem">
<Label> building: </label>
<Input name = "RoomName" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>
</Div>
<Div class = "fitem">
<Label> Department: </label>
<Input name = "RoomName" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>
</Div>
<Fieldset>

<Input type = "checkbox" id = "ktkzq" name = "ktkzq" value = "ktkzq"/>

<Div class = "fitem">

<Input name = "kt_dk" id = "kt_dk" disabled = "disabled" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>
</Div>
<Div class = "fitem">

<Input name = "kt_dz" id = "kt_dz" disabled = "disabled" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>
</Div>
<Div class = "fitem">

<Fieldset>

<Div class = "fitem">

<Input name = "dg_dk" id = "dg_dk" disabled = "disabled" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>
</Div>
<Div class = "fitem">
<Label> address: </label>
<Input name = "dg_dz" id = "dg_dz" disabled = "disabled" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>

<Div class = "fitem">

</Div>
<Div class = "fitem">
<Label> enable or not: </label>
<Input name = "dg_sfqy" id = "dg_sfqy" disabled = "disabled" class = "easyui-combobox" style = "padding: 2px; width: 141px;" required/>
</Div>
</Fieldset>
<Div class = "fitem">

</Div>
</Form>

Isn't it a lot? If you want to write every input, do you want to vomit blood?
Let's look at my method. First, we take down all the names and values of input,
The js Code is as follows:
Var str_data = $ ("# dlg_form input"). map (function (){
Return ($ (this). attr ("name") + '=' + $ (this). val ());
}). Get (). join ("&");

Alert (data );

Ps: You alert, you will find that the architecture here is divname = xxx & divname2 = xxxx, etc,

Then let's look back at what ajax submitted:

$. Ajax ({
Type: "POST ",
Url: "some. php ",
Data: "name = John & location = Boston ",
Success: function (msg ){
Alert ("Data Saved:" + msg );
}
});

Have you found that we only need to put the obtained data in data?

 

The complete code should be

$. Ajax ({var str_data = $ ("# dlg_form input"). map (function (){
Return ($ (this). attr ("name") + '=' + $ (this). val ());
}). Get (). join ("&");
Type: "POST ",
Url: "some. php ",
Data: str_data,
Success: function (msg ){
Alert ("Data Saved:" + msg );
}
}); OK, it's that simple. If applicable, you can use it...

Haha.
