This prevent enter submit,but at the moment prevent enter in inputs.
I need that enterkey work in inputs but not submit form.
<template id="form-template">
<form action="save-passport" #keypress.enter.prevent method="post" enctype="application/x-www-form-urlencoded" >
<input type="submit" v-show="loaded" v-on:click="saveForm" value="Save" />
<input type="text" required="required" name="field-11" >
<select required="required" name="field-13"><option value=""></option>
</select>
</form>
</template>
Had the same problem. Solution I did was to put the submit method on the opening form tag. Then no need for the input/button type="submit" inside the form at the bottom.
<form class="form" action="" method="POST" #submit.enter.prevent="createForm()">
Also other options available on inputs:
#keydown.enter.prevent
#keyup.enter.prevent
#submit.enter.prevent
I did it this way
first i removed vue modifiers from form tag.
second i chaged type of input from submit to button
and third this my saveForm function
saveForm:function(){
if (someCondition){
event.preventDefault();
}else{
document.forms[0].submit();
}
}
You need to use the prevent modifier. Another thing, your webpage itself must have the focus. Meaning, if you just visit the webpage, prevent won't work. But, if you click somewhere in the form, prevent will work for you.
You can still submit the form via JavaScript using something like document.forms[0].submit();

If I create a form using form tag helper the submit button triggers the OnPost event
<form method="post" asp-page="login">
However if I use
<form method="post" action="/auth/login">
The OnPost event is not fired.
And yes, asp-page="login" translates tp "/auth/login".
Even if I use asp-page="login" and copy the url from the console inspector and paste onto my cshtml page, a blank page is returned.
Any thoughts?
You can try to add #Html.AntiForgeryToken() into the second form.When you use the second form,it will lose a hidden input which contains the antiforgery token.
<form method="post" action="/auth/login">
#Html.AntiForgeryToken()
<input type="submit" value="submit" />
</form>
hope You all have a great day.Here I'm trying to create a form without submit buttons,but when press enter on the text-box the whole text-box gonna hide.why is this is happening?,is it actually possible to create a form without a submit button or is that is a mandatory thing?,thanks for Your valuable time.
<form >
<input type="number" name="cbarcode" id="cbarcode" autofocus/>
</form>
When you hit 'enter' it submits the form.
I believe this is a natural part of a 'form' behavior for accessibility. Input inside of a form is meant to be data the user sends or inserts somewhere which is likely the reasoning behind this.
You can add to the Html form onsubmit="return false" or return preventDefault() as an event handler / function with other handling code you may want to provide.
Try this:
<form onsubmit="return false;">
<input type="number" name="cbarcode" id="cbarcode" autofocus/>
</form>
I have a simple (mostly-working) submission form:
<form action="http://127.0.0.1:3000/books" method="POST" class="addBook">
<input type="text" placeholder="Title" name="title" required>
<input type="text" placeholder="ISBN" name="isbn" required>
<button id="submitBook" type="submit" onclick="addingBooks()">Submit</button>
</form>
My form properly adds the input values to my database and it then appears in the DOM when I go back and refresh the page.
I have applied an preventDefault() function in my JavaScript code for the 'addingBooks()' function to stop it from submitting twice, but I am still unable to stop it from forwarding to the action page after submission which only shows the JSON of the submitted data.
If you need more then please let me know.
To prevent the default action of an event you'll need an event object to call preventDefault on. Some browser do in fact have a global event object but that might not be reliable.
The simplest option would be to return false from the onlick event, not from a function you call in it
<button id="submitBook" type="submit" onclick="addingBooks();return false;">Submit</button>
another simple and better solution would be to make the button be a regular button instead of a submit button and remove the preventDefault from addingBooks.
<button id="submitBook" type="button" onclick="addingBooks()">Submit</button>
another and even better solution would be to not use the onclick attribute at all, use the addEventListener function
document.getElementById('submitBook').addEventListener("click", function(e){
e.preventDefault();
//other stuff
});
I know how to detect which submit button was clicked when I know the name values of each of the buttons. But what if the names are dynamic or defined by another component?
For example, here I can simply check the POST data from this <form> for either alpha or bravo:
<form>
<input type="submit" name="alpha" value="Alpha">
<input type="submit" name="bravo" value="Bravo">
</form>
But that's only because I know I should be looking for those names.
Is there a best practice for handling this type of situation? (Perhaps by rendering an element <input type="hidden" name="submit-button-names" value="dynamic_name1|dynamic_name2|etc">.) I would like a solution that doesn't require JavaScript.
Presuming you have control over the JSP displaying these buttons, just prefix the button names with a string you can look for in the POSTed data. For example prepending "dynamicbutton_" to all of the names like this
<form>
<input type="submit" name="dynamicbutton_alpha" value="Alpha">
<input type="submit" name="dynamicbutton_bravo" value="Bravo">
</form>
Then in your Servlet, look for values with this prefix by calling ServletRequest.getAttributeNames()
You could write a custom tag to set the different inputs to your form based on a list of parameters you give to the tag.
You would end up with the HTML looking something like this:
<form method="POST" action="SelectColour.do">
<p>Select your favorite colour: </p>
<formTags:select name='colour' size='1' optionsList='${applicationScope.colourList}'/>
<input type="SUBMIT" value="Click here to submit">
</form>
Here's a decent guide to creating custom tags.
I have a form where I have a search functionality with a text box(TextBox1) and a submitt button(Button1). Apart from search, there is another set of textbox(TextBox2) and submitt button(Button2). When I write something in search box(TextBox1), and hit enter, the validation message of the second textbox(TextBox2) is shown.
I am not sure how to bind the respective textboxes with submitt buttons. Please help.
Thanks in advance
Depending on how much control you have, the easiest way would be to have separate forms for each texbox/button combo.
<form action="dosomething.php">
<input type="text" name="foo" />
<input type="submit" />
</form>
<form action="dosomethingelse.php">
<input type="text" name="bar" />
<input type="submit" />
</form>
If you can't or don't want to do that, you'll need to look at handling the onkeydown event on the text boxes to prevent an automatic submission. Something like <input type="Text" name="foo" onkeydown="doSubmit(this); return false;" />. Note the return false;, which prevents the default action from taking place.
