The following code produces a prompt with a single input box, however i need to have two input boxes . Is this achievable ?
alertify.prompt("Please enter Values","Default Text").set('onok', function(closeevent, value) {
if (value == "" || value == " " )
{
alertify.error("No value entered");
return;
}
else
{
updateItem(selectedItem,value);
}
}).set('title',"Update Values");
So i was able to achieve this with the following code :
<!-- the content to be viewed as dialog
***Define the two input boxes
*** Note the input element class "ajs-input" that i have used here , this is the class used by AlertifyJS for its Input elements.
-->
<div style="display:none;" >
<div id="dlgContent">
<p> Enter Value One </p>
<input class="ajs-input" id="inpOne" type="text" value="Input One Default Value"/>
<p> Enter Value Two </p>
<input class="ajs-input" id="inpTwo" type="text" value="Input two default Value"/>
</div>
</div>
<!-- the script -->
<script>
var dlgContentHTML = $('#dlgContent').html();
$('#dlgContent').html("");
/* This is important : strip the HTML of dlgContent to ensure no conflict of IDs for input boxes arrises" */
/* Now instead of making a prompt Dialog , use a Confirm Dialog */
alertify.confirm(dlgContentHTML).set('onok', function(closeevent, value) {
var inpOneVal = $('#inpOne').val();
var inpTwoVal = $('#inpTwo').val();
/* Insert your code to work with the two values */
}).set('title',"Update");
</script>

I have a dialog that contains inputs,
User should complete dialog inputs then click send,
After that, user can open the same dialog again and complete dialog inputs.
But when the user open the dialog again, input values remain as same from previous inputs,
How can I remove previous input values?
My Dialog:
<dialog id="main-customers">
<h2>العملاء الرئيسيون</h2>
<div>
<label for="main-customers-name">الاسم</label>
<input type="text" id="main-customers-name" placeholder="الاسم" required>
<label for="main-customers-country">الدولة</label>
<input type="text" id="main-customers-country" placeholder="الدولة" required>
<label for="main-customers-goods">سلع / بضائع</label>
<input type="text" id="main-customers-goods" placeholder="سلع / بضائع" required>
</div>
<div class="center">
<button id="main-customers-send">إرسال</button>
<button id="main-customers-cancel" onclick="closeDialog('main-customers')">إلغاء</button>
</div>
</dialog>
My JS:
document.getElementById("main-customers-send").addEventListener("click", function(){
// to remove initial value
var no_data= document.getElementById("main-customers-table-no-data");
if(no_data){
no_data.remove()
}
// END to remove initial value
var name= document.getElementById("main-customers-name");
var country= document.getElementById("main-customers-country");
var goods= document.getElementById("main-customers-goods");
document.getElementById("main-customers-table").innerHTML+=
`<tr>
<td>${name.value}</td>
<td>${country.value}</td>
<td>${goods.value}</td>
</tr>`;
let itms = document.querySelectorAll("#main-customers");
for (let itm of itms) {
if(itm.value != ""){
itm.value= ""; //it does not do the job
}
}
closeDialog("main-customers")
})
-
values remain the same as shown below:
The line let itms = document.querySelectorAll("#main-customers"); doesn't do what you think it does. It selects all the elements with the id "main-customers" (which per spec a page could only have one of).
Try let itms = document.querySelectorAll("#main-customers input[type=text]"); instead of that which will select all the children of the #main-customers element that is an input whose type is text.
I have a drop down list with two value ("START" & "END"). Conditionnality to this drop down value, I want to display a specific DIV or another.
I tried to implement the following code but it isn't working. When I change the value in my drop down input nothing's happen.
The drop down id is : 5e64c4918c4b473a8ed1c55264aca3d9 .
HTML code :
<P align=left><FONT size=2>Choice : <SpotfireControl id="5e64c4918c4b473a8ed1c55264aca3d9" /> </FONT>
<DIV id="div1"><FONT size=2>List 1 : </FONT> <SpotfireControl id="5f252f7f373d48debc33bfde6fd7dd65" /> </DIV>
<DIV id="div2"><FONT size=2>List 2 :</FONT> <SpotfireControl id="136584e6f10143c9ade2a82f5cf4fef0" /></DIV>
<P>

<P align=left> </P>
<P><SpotfireControl id="42a0fbc386184501903389b4c48155a5" /></P>
My Javascript code is the following :
//Triggering the script if Drop Down selection is varied
$("#5e64c4918c4b473a8ed1c55264aca3d9").change(function()
{
var value = $("#5e64c4918c4b473a8ed1c55264aca3d9").val(); //To capture the index
var vt = $("#5e64c4918c4b473a8ed1c55264aca3d9").text(); //To Capture the selected text
if(vt== "START") //If the Drop Down selected value is Start
{
$("#div1").show(); //Making the Input list visible
$("#div2").hide();
}
else
{
$("#div1").hide(); //Making the Input list element hidden
$("#div2").show();
}
}
);
I've also created an iron python script that I've linked to my drop down list :
Ironpython script :
from Spotfire.Dxp.Application.Visuals import HtmlTextArea
ta.As[HtmlTextArea]().HtmlContent += " "
where ta is an input of type "Visualization".
Could you help me?
Thanks in advance
As on.click isn't supported, I have deleted on.click statement and it's working !

};
I am programming a web application which accepts barcodes from a barcode reader in an input field. The user can enter as many barcodes that s/he wants to (i.e. there is no reason for a predefined limit). I have come up with a brute force method which creates a predefined number of hidden input fields and then reveals the next one in sequence as each barcode is entered. Here is the code to do this:
<form id="barcode1" name="barcode" method="Post" action="#">
<div class="container">
<label for="S1">Barcode 1   </label>
<input id="S1" class="bcode" type="text" name="S1" onchange="packFunction()" autofocus/>
<label for="S2" hidden = "hidden">Barcode 2   </label>
<input id="S2" class="bcode" type="text" hidden = "hidden" name="S2" onchange="packFunction()" />
<label for="S3" hidden = "hidden">Barcode 3   </label>
<input id="S3" class="bcode" type="text" hidden = "hidden" name="S3" onchange="packFunction()" />
<label for="S4" hidden = "hidden">Barcode 4   </label>
<input id="S4" class="bcode" type="text" hidden = "hidden" name="S4" onchange="packFunction()" />
<label for="S5" hidden = "hidden">Barcode 5   </label>
<input id="S5" class="bcode" type="text" hidden = "hidden" name="S5" onchange="packFunction()" />
</div>
<div class="submit">
<p><input type="submit" name="Submit" value="Submit"></p>
</div>
</form>
<script>
$(function() {
$('#barcode1').find('.bcode').keypress(function(e){
// to prevent 'enter' from submitting the form
if ( e.which == 13 )
{
$(this).next('label').removeAttr('hidden')
$(this).next('label').next('.bcode').removeAttr('hidden').focus();
return false;
}
});
});
</script>
This seems to be an inelegant solution. It would seem to be better to create a new input field after each barcode has been entered. I have tried creating new input elements in the DOM using jQuery, and I can get the new input element to show. But it uses the onchange event, which detects changes in the original input field. How do I transfer focus and detect onchange in the newly created input field? Here is the code that I have played with to test out the idea:
<div>
<input type="text" id="barcode" class="original"/>
</div>
<div id="display">
<div>Placeholder text</div>
</div>
<script src="./Scripts/jquery-2.2.0.min.js"></script>
$(function () {
$('#barcode').on('change', function () {
$('#display').append('<input id='bcode' class='bcode' type='text' name='S1' autofocus/>')
});
});
</script>
Once I have these barcodes, I pack them into array which I then post them to a server-side script to run a mySQL query to retrieve data based on the barcodes, and then post that back to the client. So part of what I have to achieve is that each barcode that is entered into the different input fields need to be pushed into an array.
Is there an elegant way to accomplish the creation of input fields dynamically and then detecting changes in those to create yet more input fields?
The dynamic update you have tried out is all right. If you must push it into an array on submit you have to prevent default of form submit, serialize the form and then make an ajax request.
Heres an example:
$('form').on('submit',function(e){
e.preventDefault();
var formData = $(this).serializeArray();//check documentation https://api.jquery.com/serializeArray/ for more details
$.ajax({
type:'post',
url:<your url>//or you could do $('form').attr('action')
data:formData,
success:function(){}//etc
})
});
If you do not display the barcodes in the html you can skip the input fields and store the read barcodes in an array[]. Not everything that happens in javascript has to be displayed in the website (View) . i do not know what code you use to scan the barcode but you do not need the input-elements at all.
See the example on this site https://coderwall.com/p/s0i_xg/using-barcode-scanner-with-jquery
instead of console.log() the data from the barcode scanner can simply be saved in an array[] and be send from there.
If you want to create elements dynamcially see this thread: dynamically create element using jquery
The following code adds the p-element with the label "Hej" to the div "#contentl1"
`$("<p />", { text: "Hej" }).appendTo("#contentl1");`
UPDATE: I added some simple CSS to make each input field display on its own line.
Here's one strategy:
Listen for the enter/return key on the input box.
When the enter/return key is pressed (presumably after entering a barcode), create a new input box.
Stop listening for the enter key on the original input and start listening for it on the new input.
When a "submit all" button is pressed (or when tab is used to shift the focus from the most recent input to the "submit all" button and enter is pressed), then collect all the input values in an array.
$(function() {
var finishBarcode = function(evt) {
if (evt.which === 13) {
$(evt.target).off("keyup");
$("<input class='barcode' type='text'/>")
.appendTo("#barcodes")
.focus()
.on("keyup", finishBarcode);
}
};
var submitBarcodes = function(evt) {
var barcodesArr = $(".barcode").map(function() {
return $(this).val();
}).get();
$("#display").text("Entered Barcodes: " + barcodesArr);
};
var $focusedInput = $('.barcode').on("keyup", finishBarcode).focus();
var $button = $('#submitAll').on("click", submitBarcodes);
});
input.barcode {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>Type barcode into input box</li>
<li>To enter barcode and allow new entry, press Return</li>
<li>To submit all barcodes, either press tab and then return or click Submit button</li>
</ul>
<div id="barcodes"><input type="text" class="barcode" /></div>
<div><button id="submitAll">Submit all barcodes</button></div>
<div id="display">Placeholder text</div>
I'm having a bit of trouble with this assigment and would like your help.
We are meant to create a product registration form page with all the regular expressions and everything and display the correct error when the regexes don't match.
I am trying to print a tick or say OK next to a form field but I can't get the right function. My form right now looks like this: http://www.imageurlhost.com/images/98zrdmrmsvbxnwowrvsf.png
The "Please enter product ...." is activated by jquery with a slideUp and slideDown function with onblur on the text field.
So I want to display OK where the red circle is after you click away from it, and then if you change it to something that doesn't match the OK disappears and my alert shows up. So this is my code so far:
My html form:
<div>
<input type="text" class="name" placeholder="Name" name="name" onblur="return validateProductName()"> <p class ="p11" id="p1"></p>
<p class="name-help">Please enter a product name between 1-50 characters.</p>
</div>
My css:
.p11 {
float: right;}
My jQuery:
$(".name").focus(function(){
$(".name-help").slideDown(500);
}).blur(function(){
$(".name-help").slideUp(500);
});
And then my JavaScript:
// Function to validate product name
function validateProductName() {
// if statement for product name
if (document.myForm.name.value.trim().search(pName) == -1) {
alert("Invalid product name. Please note: product name should have 1-50 characters.");
} else {
document.getElementById("p1").innerHTML = "OK";
}
}
So, it prints the OK in between the field on the right side, but I want it right next to the field like I showed in the picture and I can't get this to work! I want it to disappear if I go back to the form and put something wrong...
Thanks guys!
I assume, you have no problem with the jQuery itself, you have a problem of showing it next to input box. So,
Create a <span id='tick'> tag after the input field
And once it passes the validation, use jquery to show the tick
$('#tick').html('whatever you want');
EDIT: You dont have to include the float:left on span
Check out the fiddle link
EDIT:
In this validation function, just show and hide according to the validation results
// Function to validate product name
function validateProductName() {
// if statement for product name
if (document.myForm.name.value.trim().search(pName) == -1) {
document.getElementById("tick").style.display = 'none'; // to hide the OK text if enterd the wrong input
} else {
document.getElementById("tick").innerHTML = "OK"; //NOTE: This is for showing the ok text
document.getElementById("tick").style.display= "block";
}
}
Create a span wherever you want your tick to be displayed and they do this,
$("#btn").click(function() {
if ($("#txtname").val() == "") //can be any check
{
$("#g").attr("style", "display:block;width:20px");
} else {
$("#g").attr("style", "display:none;width:20px;");
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="text" id="txtname" style="display:inline-block" placeholder="enter name" />
<img id="g" style="width:50px;display:none;" src="http://pixabay.com/static/uploads/photo/2014/04/02/10/19/check-303494_640.png" />
<br/>
<input type="button" id="btn" value="click to submit" />
This should work-
<script src="jq.js"></script>
<div>
<input type="text" class="name" placeholder="Name" name="name" id="input"> <span class ="p11" id="p1"></span>
<p class="name-help">Please enter a product name between 1-50 characters.</p>
</div>
<style>
p11 {
float: right;}
</style>
<script>
$(".name").focus(function(){
$(".name-help").slideDown(500);
}).blur(function(){
$(".name-help").slideUp(500);
validateProductName()
});
</script>
<script>
// Function to validate product name
function validateProductName() {
// if statement for product name
if (document.getElementById("input").value.trim() == "" || document.getElementById("input").value.length > 50 ) {
alert("Invalid product name. Please note: product name should have 1-50 characters.");
document.getElementById("p1").innerHTML = "";
} else {
document.getElementById("p1").innerHTML = "OK";
}
}
</script>
I am creating a set of textboxes dynamically while pressing (+) button, by cloning the following HTML template:
<div id= "other_leaders" class="controls form-input">
<input type="text" name="other_leader_fname[]" class="input_bottom other_leader_fname" id="other_leader_fname" placeholder="First Name" value="'.$val[0].'" />
<input type="text" name="other_leader_lname[]" class="input_bottom other_leader_lname" id="other_leader_lname" placeholder="Last Name" value="'.$val[1].'" />
<input type="text" name="other_leader_email[]" class="other_leader_email" id="other_leader_email" placeholder="Email Address" value="'.$val[2].'" />
<input type="text" name="other_leader_org[]" class="other_leader_org" id="other_leader_org" placeholder="Organisation/College" value="'.$val[3].'" />
<span class="remove btn"><i class="icon-minus"></i></span>
</div>
I am able to do single textbox validation by following code:
$("input[name*='other_leader_fname']").each(function(){
if($(this).val()=="" || !RegExpression.test($(this).val()))
{
$(this).addClass('custom-error')
fnameflag = 0;
}
});
Now my question is how to do empty validation for all four textboxes, if any one textbox field is filled by the user in that particular textbox group.
for example: if i enter values in the <div> with id other_leader_fname, then it should perform empty validation for other three textboxes of this particular group.
how can i do it?
Try this , You can apply your validation rules to all the text box in the div by using following code:
$("#other_leaders :input[type='text']").each(function(){
if($(this).val()=="" || !RegExpression.test($(this).val()))
{
$(this).addClass('custom-error')
fnameflag = 0;
}
});
As you have just one element so there is no need to have a loop over it:
var $othLeader = $("input[name*='other_leader_fname']");
if($othLeader.val()=="" || !RegExpression.test($othLeader.val())){
$(this).addClass('custom-error');
fnameflag = 0;
}
And if you have form then you can validate this in your form's submit function.
You can iterate over the .controls using the each() and check for filled inputs in each group using filter for performing the validation as follows:
$('.controls').each(function(){
var $inputs = $(this).find('input');
var filled = $inputs.filter(function(){
return this.value != "";
});
if(filled.length){
$inputs.each(function(){
if($(this).val()=="" || !RegExpression.test($(this).val()))
{
$(this).addClass('custom-error')
fnameflag = 0;
}
})
}
});
Demo
side note: since the above is a template for dynamically generated content, You should remove the id and use class instead since id should be unique in a document.
