I need some help with the following issue. I am pretty new to JavaScript so this one is pretty tough for me. Any help would be greatly appreciated!
We have a form for registration that is already in use and I need to make some amends to it to enhance its usability. The form itself already contains several validation scripts and I need to add in a new one - an error message to appear next to the mobile field. I am unable to amend the form HTML itself so I have to do everything by javascript – I need to bind the new function to the submit button so that it fires AFTER all the other validations (field highlight, pop ups), but before the page turns over.
Here is the form (I have just left in the feild i need to amend) :
<form method="post" action="#" id="register_form" class="validate">
<input type="hidden" name="page" value="" />
<input type="hidden" name="unregistered" value="false" />
<fieldset>
<legend>I am a new online customer</legend>
<div class="element">
<label for="mobile_number">Mobile:**</label>
<input name="mobileNumber" type="text" id="mobile_number" title="Please enter at least one number" class="text validate {validate:{minLength:10, eitherOr:'#telephone_number', messages:{minLength:'Please enter a valid phone number (at least #NUM digits long)', eitherOr:'Please enter either your Telephone or Mobile number'}}}" />
</div>
<div class="element continue_shopping_cont submit">
<button type="submit" class="submit button small_button"><span>Register</span></button>
</div>
<input type="hidden" name="secure_from" value="" />
</fieldset>
</form>
Could someone help show me how i am supposed to do this and how is best to target this field?

I have a form and I want to set default value in the field below but it's not working.
<span>ID User:</span>
<input type="text" th:value="${session.name}" th:field="*{userid}" th:errorclass="field-error" />
</div>
<div>
<span class="name-in">ID Room:</span>
<input type="text" th:value="${id}" th:field="*{room}" th:errorclass="field-error" />
</div>
I read some topic about this problem and I try to change as given below
th:attr="value = ${session.name}"
But It's still not working. Field ID User is empty. I don't know how to solve this problem.
Although your question contain less information, but i think you want to put default value for all field. If you like to do so change
`<input type="text" th:value="${session.name}" th:field="*{userid}" th:errorclass="field-error" />`
to
<input type="text" name="userid" value="as your wish" th:errorclass="field-error" />
Instead of changing the html, you should instead set the value of *{userid} in your controller. That way you can keep your html the same:
// Controller
modelObject.setUserId(session.name);
// HTML
<input type="text" th:field="*{userid}" th:errorclass="field-error" />
I'm currently trying to add validation to an angular 2 form, but for some reason I can't get my submit button to disable when the required fields are not filled in.
Here is the code of my form template:
<h1 md-dialog-title>{{title}}</h1>
<form #formCtrl="ngForm">
<md-dialog-content>
<md-input-container>
<input #name md-input placeholder="Name" value="" name="name" focused required>
</md-input-container>
<br />
<md-select #inputtype placeholder="Input type" name="inputtype">
<md-option *ngFor="let inputtype of inputtypes" [value]="inputtype.id">
{{inputtype.name}}
</md-option>
</md-select>
</md-dialog-content>
<md-dialog-actions>
<button type="submit" md-raised-button color="primary" [disabled]="!formCtrl.form.valid">Create</button>
</md-dialog-actions>
</form>
According to several examples, this should work, however the button is never disabled. I've also tried "!formCtrl.valid", also to no avail.
I've tried using non-material design input fields thinking maybe that would be the issue, but it still won't work.
I then tried copy/pasting the following simple example into my application, and even that won't work at all:
http://blog.angular-university.io/introduction-to-angular-2-forms-template-driven-vs-model-driven/
Any ideas as to what might prevent it from working correctly?
Assuming you are using a newer release than Angular 2 final:
You need to add ngModel, which binds the form value based on the name attribute’s value. In your case one is name="inputtype" the other is name="name". So you need to add ngModel to bind the values, and your form should work as you wish! :)
So the following should work (removed a bit of noise from code):
<form #formCtrl="ngForm" (ngSubmit)="save(formCtrl.value)"> //whatever your submit method is
<md-dialog-content>
<md-input-container>
<input md-input name="name" required ngModel>
</md-input-container>
<md-select name="inputtype" required ngModel>
<md-option *ngFor="let inputtype of inputtypes" [value]="inputtype.id">
{{inputtype.name}}
</md-option>
</md-select>
</md-dialog-content>
<md-dialog-actions>
<button type="submit" md-raised-button color="primary" [disabled]="!formCtrl.form.valid">Create</button>
</md-dialog-actions>
</form>
Don't remember when this was introduced, this should be found somewhere in the changelogs which can be useful to have a look at once in a while, since Angular is constantly tweaking things almost in every release. So following that will keep you updated with changes and syntax :)
I have this simple kendo-template script:
<!-- popup editor template -->
<script id="userEditor" type="text/x-kendo-template">
<div id="popServerErrorSummaryPlaceholder" style="display:none"></div>
<div class="control-row">
<label class="span2" for="FirstName">Vorname</label>
<input Id="FirstName" class="span4" data-bind="value:FirstName" maxlength="50" name="FirstName" required="true" type="text" />
<span class="k-invalid-msg" data-for="FirstName"></span>
</div>
<div class="control-row">
<label class="span2" for="LastName">Nachname</label>
<input Id="LastName" class="span4" data-bind="value:LastName" maxlength="50" name="LastName" required="true" type="text" />
<span class="k-invalid-msg" data-for="LastName"></span>
</div>
</script>
Which is used while editing a single row within the Kend-UI grid.
I have got right now two issues:
a) The documentation states that I can control the position for validation messages via a "span" element that has a class "k-invalid-msg".
The behaviour right now is that this span Element gets replaced with a div element and it is positioned below the label element. I would like to get the message next to the input.
b) The validation is triggered immediately when the pop up is displayed.The validation should be trigger either when leaving the input or clicking the "update" button.
Someone out there who can help me here?
Things I am not quite sure how to handle:
c) Some validations are performed at the server. I get them back to the browser via the DataSource error event (custom JSON which is basically a list of field name and associated error messages). I would like to display the error messages within the validation span. I can create custom validation rules as documented here.
How do I get the validator that is associated with the pop up editor window? Or is there foreach input a validator created?
Anyone did this before?
Thanks for any help!
Updates:
regarding to point a)
OnaBai pointed me to the right direction. Thanks for that.
I am trying to invoke a form submit using javascript (jquery) to invoke a webflow transition. It works and the submit invokes the desired transition. But, the updated radio button values is not reflected on the model object which is posted.
Here is the code:
<form:form method="post" action="#" commandName="infoModel" name="pageForm">
<form:input type="input" path="testMsg" id="success" />
<input type="button" id="clearSelections" value="Clear Selections">
<div class="question">
<h4><c:out value="${infoModel.questionInfo.description}"/> </h4>
<form:radiobuttons path="infoModel.answerId"
itemValue="answerId" itemLabel="answerDescription" items="${infoModel.answers}" delimiter="<br/>" />
</div>
<input type="submit" name="_eventId_saveQualitativeInput" value="Save" id="save" />
$(document).ready(function() {
$('#tabs').tabs();
//Clear selections (copy is server-side)
$('#clearSelections').click(function() {
//$('input[type="radio"]').prop('checked', false);
$('input[type="radio"]').removeAttr('checked');
$('#save').trigger('click');
});
});
</form:form>
The form:radiobutton, generates the below html:
<div class="question">
<h4>Is this a general obligation of the entity representing a full faith and credit pledge? </h4>
<span>
<input type="radio" checked="checked" value="273" name="infoModel.answerId" id="infoModel.answerId1">
<label for="infoModel.answerId1">Yes</label>
</span>
<span><br>
<input type="radio" value="274" name="infoModel.answerId" id="infoModel.answerId2">
<label for="infoModel.answerId2">No</label>
</span>
<br>
<span class="error"></span>
</div>
The input id= "success" value is registered and when the control goes to the server, the value of input id= "success" is updated in the "infoModel" object. But the value of answerId is not updated on the "infoModel" object.
Thoughts if i am missing something in the form:radiobutton element or if there is something else wrong?
Thanks in advance!
EDIT:::::::
Thanks mico! that makes sense. I stripped of some of the code first time to make it precise, but i have a list which is being used for building the radio-buttons, below is the code:
<c:forEach items="${infoModel.list["index"]}" var="qa" varStatus="rowCount">
<div class="question">
<h4><c:out value="${question.questionInfo.description}"/> </h4>
<form:radiobuttons path="list["index"][${rowCount.index}].answerId" itemValue="answerId" itemLabel="answerDescription" items="${question.answers}" delimiter="<br/>" />
<br>
</div>
</c:forEach>
Could you please suggest how i could try this one out?
NOTE: The same code works on a regular form submit on click of a button of type submit. Its the javascript form submit which is not working. I also tried to do whatever i want to do in javascript and then invoke the button.trigger('click'); form got submitted but the changes made on form in my javascript didnt reflect.
With commandName inside a form:form tag you set "Name of the model attribute under which the form object is exposed" (see Spring Documentation). Then in path you should tell the continuation of the path inside the model attribute.
With this said I would only drop the extra word infoModel from path="infoModel.answerId" and have it rewritten as path="answerId" there under the form:radiobutton.
I am successfully validating and arresting the submission of a form using Validate by the bassistance.de guy.
Problem is, I am halting submission too much as there is a hidden set of inputs which requires validation only if ONE other radio button is checked.
I am calling my validation scheme from a remote script on page load and I was "TRYING" to remove the validation rule on the form page when the contingent element is clicked.
Thing is, the page acts as though the rule is still there.
Here's some pseudo:
<html>
<head>
<script src="jquery.js"></script>
<script src="jq.validate.js"></script>
<script src="formproc.js"></script>
</head>
<body>
<form method="" action="" id="whatever">
<input type="radio" name="answer" value="1008" id="yes" /><label for="yes">Yes</yes>
<input type="radio" name="answer" value="1009" id="no" /><label for="no">No</label>
<input type="radio" name="answer" value="1010" id="un" /><label for="un">Not sure</label>
<div id="somedivthatshidden">
<input type="radio" name="nother" value="1009" id="ok" /><label for="ok">OK</label>
<input type="radio" name="nother" value="1010" id="noway" /><label for="noway">No Way</label>
</div>
<script src="jQ_funx_that_handle_the_show_hide_etc.js"></script>
<input type="submit" value="doit" />
</form>
</body>
</html>
So, when the user clicks on any of the FIRST 3 radio buttons that DO NOT reveal "SOMEDIVETHATSHIDDEN", I also call for the rule removal. Is this wrong?
I've tried putting the rule removal inline in the document, at the end of my function listing, so on and so forth... no dice. Still hangs on that required second set of radios even if they're not displayed
Thanks much,
Rob
You can use depends config option to make a field conditionally required.
