I'm using Thymeleaf. I would like to make a form where numbers are thousand-separated. Here is my code:
<form action="#" id="postForm" th:action="#{/foo/update}"
<!-- other fields -->
<label for="barNumber" form="postForm">Number of bars</label>
<input id="barNumber" type="number" th:field="#numbers.format(*{barNumber}, 3, 'COMMA')" required="required">
</form>
It threw me error. I also tried:
<input id="barNumber" type="number" th:field="${numbers.formatInteger(*{barNumber}, 3, 'COMMA')" required="required">
It was also unsuccessful.
How could I solve this problem?

I use Bootstrap 4.5, where it is possible to check the filling of the form, for example by inserting required.
<input type="text" class="form-control" name="name_1" required>
How can I please check where I need to have input #1 OR input #2 filled in?
<input type="text" class="form-control" name="name_1">
<input type="text" class="form-control" name="name_2">
if you want to check whether the input#1 OR input#2 is filled. I recommend you to write a piece of javascript code to check that. if you are familiar with java script, create a separate javascript file and write a function to validate. or else you can just put a script tag inside the head tag as follows.
Javascript Validation:
<head>
<script>
function validateForm(){
if(document.myform.input1.value == "" || document.myform.input2.value == ""){
alert("Both input1 and input2 should not be empty!");
}
}
</script>
</head>
HTML form:
<form name="myform" method="post" onsubmit="validateForm()" >
Input1: <input type="text" name="input1"><br/>
Input2: <input type="text" name="input2"><br/>
<input type="submit">
</form>
I have an input field in a form which is filled but disabled (I am trying to build details view). In the code below titleAccessor.valid returns false.
Any ideas how to overcome this issue ?
<div class="form-group row">
<label class="col-md-3 form-control-label" for="title">{{'contentSalesTextConfig.titleForm'|translate}}</label>
<div class="col-md-9">
<input [disabled]="pageStatus==4" required [ngClass]="{'redBorder': ((titleAccessor.touched||formSubmitted)&&!titleAccessor.valid)}" [ngModel]="textContentMain.title" #titleAccessor="ngModel" name="title" id="title" type="text" class="form-control" placeholder="{{'contentSalesTextConfig.placeHolder.titleForm'|translate}}">
</div>
</div>
NOTE: When i remove [disabled]="pageStatus==4" validation works as it is supposed to..
disabled inputs are considered as invalid inputs , you can use readonly instead of disabled :
<input [readonly]="pageStatus==4" required [ngClass]="{'redBorder': ((titleAccessor.touched||formSubmitted)&&!titleAccessor.valid)}" [ngModel]="textContentMain.title" #titleAccessor="ngModel" name="title" id="title" type="text" class="form-control" placeholder="{{'contentSalesTextConfig.placeHolder.titleForm'|translate}}">
hope this will help :)
I am using template driven forms for adding the task, and there are 2 input fields of type number for estimated mins to complete task,
one field is for estimated number of hrs and
another is for estimated minutes to complete the task
since the task estimate can be done either in hours like 1hrs , or in hours and minutes like 1Hrs 30Mins , so i want to set attribute required to inputs conditionally. So one of the 2 inputs must be set or form validation error will occur if both inputs are empty when submitting form.
so far i have done this but validation is not working
<form class="add-task" (ngSubmit)="onSubmit(newtask)" #newtask="ngForm">
<div class="estimate-container">
<input
type="number"
min="0"
max="10"
id="estimate_hrs"
ngModel
name="estimate_hrs"
mdInput
[required]="!estimateMins.valid"
placeholder="Estimated Hours"
#estimateHrs="ngModel"
>
<div class="error-msg" *ngIf="!estimateHrs.valid && !estimateMins.valid">
Please enter estimated hours
</div>
<input
type="number"
min="0"
max="60"
id="estimate_min"
ngModel
name="estimate_min"
mdInput
[required]="!estimateHrs.valid"
placeholder="Estimated Minutes"
#estimateMins="ngModel"
>
<div class="error-msg" *ngIf="!estimateMins.valid && !estimateHrs.valid">
Please enter estimated minutes
</div>
</div>
<button type='submit' [disabled]="!newtask.valid" >Submit</button>
</form>
Try using [attr.required] instead.
<input
type="number"
min="0"
max="10"
id="estimate_hrs"
ngModel
name="estimate_hrs"
mdInput
[attr.required]="!estimateMins.valid"
placeholder="Estimated Hours"
#estimateHrs="ngModel"
>
This is my working solution for Angular 5:
In component:
#Input()
required: boolean;
In template on the input (or select) element that:
[required]="required"
On the selector:
[required]="true"
Like #DeborahK double checked, no need for single quotes :-)
You need to put your !estimateMins.valid in single quotes like:
[required]="'!estimateMins.valid'" and [required]="'!estimateHrs.valid'"
See this plunkr
I spent some time trying this out because the basic syntax should have worked. I initially did a simply plunker just to test the syntax and the syntax does indeed work as defined.
After expanding the plunker to more closely match the OP's code: https://plnkr.co/edit/QAqeBYrg19dXcqbubVZ8?p=preview
<Links to plunker must be accompanied by code>
It became apparent that it is not a syntax error. Rather it is a logic error.
When the form first appears, both controls are valid so neither of them have the required attribute. So then neither are required and it appears that it does not work.
There are several possible ways to resolve this. One is to build a custom validator that does the cross field validation.
You can use [required]=boolean.
In angular2 or above you can use ngNativeValidate directive for template driven form. And also object to reserved and sending data(though it's your personal choice but i love this way) to api.
<form class="add-task" #newtask="ngForm" ngNativeValidate (ngSubmit)="onSubmit()">
<div class="estimate-container">
<input
type="number"
min="0"
max="10"
id="estimate_hrs"
name="estimate_hrs"
mdInput
[required]="!taskModel.estimateMins"
placeholder="Estimated Hours"
[(ngModel)]="taskModel.estimateHrs">
<div class="error-msg" *ngIf="!taskModel.estimateHrs && !taskModel.estimateMins">
Please enter estimated hours
</div>
<input
type="number"
min="0"
max="60"
id="estimate_min"
name="estimate_min"
mdInput
[required]="!taskModel.estimateHrs"
placeholder="Estimated Minutes"
[(ngModel)]="taskModel.estimateMins">
<div class="error-msg" *ngIf="!taskModel.estimateMins && !taskModel.estimateHrs">
Please enter estimated minutes
</div>
</div>
<button type='submit' [disabled]="!newtask.valid" [isFormValid]="!newtask.valid">Submit</button>
</form>
In .ts file
taskModel: any;
onSubmit(){
console.log(this.taskModel) // this object has all data.
}
You can also achieve the same with in AngularJS (version 1.x)
<form id="form" name="form" class="add-task" ng-init="taskModel={}">
<div class="estimate-container">
<input
type="number"
min="0"
max="10"
id="estimate_hrs"
name="estimate_hrs"
mdInput
ng-required="!taskModel.estimateMins"
placeholder="Estimated Hours"
ng-model="taskModel.estimateHrs">
<div class="error-msg" ng-if="!taskModel.estimateHrs && !taskModel.estimateMins">
Please enter estimated hours
</div>
<input
type="number"
min="0"
max="60"
id="estimate_min"
name="estimate_min"
mdInput
ng-required="!taskModel.estimateHrs"
placeholder="Estimated Minutes"
ng-model="taskModel.estimateMins">
<div class="error-msg" ng-if="!taskModel.estimateMins && !taskModel.estimateHrs">
Please enter estimated minutes
</div>
</div>
<button ng-disabled="form.$valid" ng-click="form.$valid && onSubmit()" >Submit</button>
</form>
Hope it's helpful to you!
Here's what I have, below, trying to use bits from similar answers here, plus items from the parsley site.. Nothing happens..User is not alerted that at least 1 box must be checked. Do I have this all wrong? Thank you in advance for any clues!
<form action="success.html" id="contact-form" data-parsley-validate>
<label for="language">Please Choose your Language:<br>
<input type="checkbox" class="checkbox" name="language" value="english" parsley-group="language" parsley-mincheck="1">English<br>
<input type="checkbox" class="checkbox" name="language" value="spanish" parsley-group="language" >Spanish<br>
<input type="checkbox" class="checkbox" name="language" value="french" parsley-group="language" >French
</label>
You have some problems with your code:
parsley-group doesn't exist. There is a data-parsley-group and is applicable if you want to validate a portion of your form.
parsley-mincheck="1" doesn't exist. There is a data-parsley-mincheck="1".
Assuming that you require at least one language, but can accept more, this code should do the trick:
<form action="success.html" id="contact-form" data-parsley-validate>
<label for="language">Please Choose your Language:<br>
<input type="checkbox" class="checkbox" name="language[]"
value="english" required>English<br>
<input type="checkbox" class="checkbox" name="language[]"
value="spanish" required>Spanish<br>
<input type="checkbox" class="checkbox" name="language[]"
value="french" required >French</label>
<button type="submit" id="submit-button">Submit form</button>
</form>
$(document).ready(function() {
// bind parsley to the form
$("#contact-form").parsley();
// on form submit, validate form and, if valid, show valid in the console
$("#contact-form").submit(function() {
$(this).parsley("validate");
if ($(this).parsley("isValid")) {
console.log('valid');
}
event.preventDefault();
});
});
If you want the user to select one and only one option, I advice you to use radio buttons.
I'm new to JSP and this is quite confusing to me.
In Php I can do something like this :
<FORM METHOD="POST" ACTION="LoginFormAction.php">
<INPUT TYPE="TEXT" NAME="username" SIZE="16">
and then use this to get what was in the TextBox :
$_POST['username'];
The current equivalent I have in Jsp is :
<form action="checkLogin.jsp">
<input name="username" size=15 type="text" />
How can I get what is in the TextBox once I submit my form ?
You can just use: request.getParameter("username").toString()
