JavaScript无法停止页面加载

Question

I have a sign-up page having proper validation's every place. But whenever i click "Sign-Up" on a blank form. It shows the validation, but gets loaded. I want to stop the loading. How's that possible.

I am primarily checking on chrome, where i checked on settings, whether javascript is disabled or not, but it is enabled.

it's happening in an .cshtml page.

Feel free to ask any question

Answer 1

If you are using validation, you must place the if condition.

For example:

 a = validate('something'); (validate - is the validation function, but you can have another name of function) if (!a) { return false; } else { --your form submit here-- } 

Answer 2

首先可能是您使用<button type="submit"> ..这将强制提交表单，即加载您必须使用<input type="button"> ，然后将验证写为@llkin建议使用return false停止加载页面

Answer 3

<form name="myForm" id="myFormId" onsubmit="myFunction()" novalidate>

</form>

myFunction(){
//you logic goes here
document.getElementById('myFormId').submit();
}

use novalidate attribute to disable to default validation of form and you can use custom function to validate on submit. In myFunction() define your custom logic to validate and submit the form.

Answer 4

DO not use button type submit. Onclick call a function where you have to validate all fields and return true/false. Call that function in your validation function check the value if true submit form.

May be this helps you.
