The Easiest Form Validation - JQuery Validation
I tried to use JQuery Validation. That is the easiest form validation library!!!!!
I just need to include the jquery library and its js file. Then I add these code in $(document).ready
Code
$([form element]).validate({rules: { | |
[field name]: { | |
[built-in Validation methods] | |
... | |
} | |
} | |
}); |
This is the validation rule.
I think that is easier to explain in an example.
I got a form like this:
Code
<form id="frm" method="POST"> | |
Name : <input type="text" id="name" name="name" /> <br/> | |
Email: <input type="text" id="email" name="email" /> | |
<input type="submit" id="submit" value="Submit"/> | |
</form> |
Then I just need add those code in $(document).ready
Code
$("#frm").validate({rules: { | |
email: { | |
required: true, | |
email: true | |
}, | |
name: "required" | |
} | |
}); |
Then the form will be validated when the user submits the data.
ERROR: Unknown option '--no-crunch' in Eclipse
I got an error in Eclipse, ERROR: Unknown option '--no-crunch' in Eclipse. I cannot start the emulator. The reason is I updated ADT plug-in in Eclipse. But I have not update the SDK at the same time.The new ADT Plug-in used the new option in SDK.
The solution is simple, please click SDK Manager in Eclipse, it will update itself. Remember the option,"Help->Check for updates", won't update your SDK. It will only update the ADT plug-in.
