Extjs form validate form verification experience

Extjs Form Verification
// Put it in function () {} of onready
Ext. quicktips. INIT (); // provides the prompt information function for the component. The main prompt information of form is the error message verified by the client.
Ext. Form. Field. Prototype. msgtarget = 'day'; // method of prompting. The enumerated value is
QTip-a prompt is displayed when you move the cursor over the control.
Title-the title is displayed in the browser, but the test result is the same as that of QTip.
Under-an error message is displayed under the control.
Side-an error icon is displayed on the right of the control. An error prompt is displayed when you point to the icon. Default Value.
ID-[element id] the error message is displayed in the HTML element of the specified ID.
1. A simplest example: Empty Verification
// Empty verification parameters
1. allowblank: false // false cannot be blank. The default value is true.
2. blanktext: String // error message when it is null
JSCode Is:
VaR form1 = new Ext. Form. formpanel ({
Width: 350,
Renderto: "form1 ",
Title: "formpanel ",
Defaults: {xtype: "textfield", inputtype: "password "},
Items :[{
ID: "blanktest ",
Fieldlabel: "cannot be blank ",
Allowblank: false, // null is not allowed
Blanktext: "cannot be blank" // error message. The default value is this field is required!
}]
});
2. Simple verification in vtype format.
In this example of email verification, rewrite the items configuration of the code above:
Items :[{
Fieldlabel: "cannot be blank ",
Vtype: "email", // verify the email format
Vtypetext: "invalid email address", // error message. I will leave it blank by default.
ID: "blanktest ",
Anchor: "90%"
}
You can modify the above vtype to the following extjs vtypes that support verification by default:
// The default supported vtype in Form Verification
1. Alpha // only letters can be entered, and other characters (such as numbers and special symbols) cannot be entered)
2. alphanum // only letters and numbers can be entered.
3. Email // email verification, the required format is "langsin@gmail.com"
4. url // URL format verification. The required format is http ://***

3. Advanced User-Defined password verification
The previous verification is provided by extjs, and we can also customize the verification function.
// Use the Ext. Apply method to add a custom password verification function (you can also use another name)
Ext. Apply (ext. Form. vtypes ,{
Password: function (Val, field) {// Val refers to the value of the text box. Field refers to the text box component.
If (field. confirmto) {// confirmto is our custom configuration parameter. It is generally used to save the id value of another component.
VaR Pwd = ext. Get (field. confirmto); // gets the value of the ID of confirmto.
Return (val = PWD. getvalue ());
}
Return true;
}
});
// Configure items Parameters
Items :[
{
Fieldlabel: "password ",
ID: "pass1 ",
},{
Fieldlabel: "Confirm Password ",
ID: "pass2 ",
Vtype: "password", // custom authentication type
Vtypetext: "The two passwords are inconsistent! ",
Confirmto: "pass1", // ID of another component to be compared
}
]
4. Regular Expression Verification
New Ext. Form. textfield ({
Fieldlabel: "name ",
Name: "author_nam ",
RegEx:/[/u4e00-/u9fa5]/, // The regular expression is in the range of [/u4e00-/u9fa5.
Regextext: "Chinese only! ",
Allowblank: false // This verification is still valid. Do not leave it blank.
