process tag before converting it into tag using bootstrap tags input

i am using bootstrap tags input in my site.
basically what i am trying to do is,
ask user to type urls into a text field, now if the text is valid url then only convert it into tag otherwise don't.
is there any way to process text before converting into tags?
any help would be appriciated.
Thanks

Bootstrap tags have beforeItemAdd event which triggered just before an item gets added. Bootstrap tags
$('input').on('beforeItemAdd', function(event) {
/* Validate url */
if (/^(?:(?:(?:https?|ftp):)?\/\/)(?:\S+(?::\S*)?#)?(?:(?!(?:10|127)(?:\.\d{1,3}){3})(?!(?:169\.254|192\.168)(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9]+)(?:\.(?:[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9]+)*(?:\.(?:[a-z\u00a1-\uffff]{2,})).?)(?::\d{2,5})?(?:[/?#]\S*)?$/i.test(event.item)) {
event.cancel = false;
} else {
event.cancel = true;
}
});

Bootstrap Tags Input have a hidden input before convert to tags you find it by following code:
$(".bootstrap-tagsinput input[type="text"]").keyup(function(){
// do your validation
});
you can see it by get an inspect element in your page. it will convert to tags after you press enter button you can do your validation until it's on hidden input.
It will be there:
<div class="bootstrap-tagsinput">
<span class="tag label label-info">Test<span data-role="remove"></span></span>
<input type="text" style="width: 7em;" size="1"> // here is!
</div>

If your input id is "tag-input", all you have to do is use a beforeItemAddcallback provided by the library itself like so:
$('#tag-input').on('beforeItemAdd', function(event) {
var tag = event.item;
if(true){ //if tag is not a url or process other text conditions.
event.cancel = true
}
});
If you don't set event.cancel to false, the add will go through.
You can check the documentation on this method here.
Also , as it is clear in this case that documentation does not say how to cancel the event. In such cases its simple enough to just check the code itself. I this case this code in the plugins github repo makes it plenty clear how to use this option.

IS Accessing DropList Value of Sitecore WFFM Control in Javascript Possible?

I am using Sitecore 7.2 with Web Forms for Marketers 2.4.
Using wffm form designer I created a form that has a droplist in it.
I want to be able to hide or unhide another field in the same form based on the selected value of the droplist. Through my research I came up with exporting the form (via form designer export) and pointing the sublayout to that exported form.
I then added and onChange event to the droplist.
<cc3:droplist runat="server" title="Country" emptychoice="True" id="field_xyz" cssclass="scfDropListBorder fieldid.%7bxyz%7d name.Country" controlname="Country" fieldid="{xyz}" enableviewstate="False" onchange="checkField()">
I then added a javascript to the bottom of the page.
function checkField() {
alert("Hello! I am an alert box!!");
var a = document.getElementById("field_xyz");
alert(a.options[a.selectedIndex].value);
var cityTextBox = document.getElementById("field_abc").parentNode.parentNode;
if (a == "United States") {
cityTextBox.style.display = "block";
} else {
cityTextBox.style.display = "none";
}
alert("Ending Script");
}
I can get the 'Hello!' alert to show every time but not the 'ending' alert and the value of 'a' is always null from what I can tell.
Is what I'm trying to do even possible in Sitecore?
I read something else that said they had a problem because of encapsulation and protection levels.
I can also confirm that when I submit the form it does show up in the WFFM reports so I know it is submitting properly.
Any help/advice/direction would be appreciated.

I've never used the export functionality so can't comment to it's effectiveness or ease of use. My suggestion would be to simply use from custom css classes and jquery on the front-end to hide/show depending on the selected value.
Create 2 new css classes under /sitecore/system/Modules/Web Forms for Marketers/Settings/Meta data/Css Classes. Call them "hide-dependent" and "dependent-field"
Add your fields and then on the country field select "hide-dependent" as the CSS class, and for the City select "dependent-field"
Add the following Javascript to your own sites js file.
The code will bind a handler to fire onchange, checked the selected value and then hide/show all field with the dependent-field class. Specifying the chained field-border ensures that we are hiding the whole row and not just the select box.
(function ($) {
var HideDependentFied = function (value) {
var condition = (value == "USA");
$(".dependent-field.field-border").toggle(condition);
};
$(document).ready(function() {
var $field = $(".hide-dependent.field-border select");
$field.on("change", function() {
HideDependentFied(this.value)
});
HideDependentFied($field.val());
});
})($scw);
The above code is using an Immediately Invoked Function Expression and passing is $scw, which is the jQuery variable used by WFFM.
You may also want to fire the function on document ready, to ensure the field is hidden on load and only shown when the appropriate value is selected.

Insert input if it does not exist

I am working on an email template editor where the user will select from a list of pre-existing templates and will be able to update the template as necessary. I had problems with using the CKEditor plugin across browsers and so I have attempted to create my own. When the user selects a template it opens in a modal window. To change the images I have included input tags which are removed upon close of the modal. This works so well and so good but if the user then wants to go back into the editor the input buttons are no longer there.
I want to add in the input button in the modal window if it does not exist. I have tried checking the length of the property but I am unable to return a value other than null whether it exists or not. My code is as follows:
function template1InputButtons() {
if ($("#imageInput1T1").length == 0) {
$('<input id="imageInput1T1" type="file" name="newImage1T1" onchange="previewImage1T1(this)" />').insertBefore('.article_media');
}
}
If I open it the first time the length comes up as one and so nothing is added as expected. If I remove and then click the button again length shows as 0 and input is added correctly as expected. If I then remove the input and click the button again the length comes up as 1 despite the control not existing.
Any ideas?

Try this:
function template1InputButtons() {
if (!$("#imageInput1T1")) {
$('<input id="imageInput1T1" type="file" name="newImage1T1" onchange="previewImage1T1(this)" />').insertBefore('.article_media');
}
}
and also assure that you have placed it inside ready function.

Try this:
if ($("body").find("#imageInput1T1").length == 0) {
$('<input id="imageInput1T1" type="file" name="newImage1T1" onchange="previewImage1T1(this)" />').insertBefore('.article_media');
}

Problem was a similar finding of class attribute article_media on the other modal my mistake thanks for the help anyway

browser auto fill event

I am doing some website where I have a login form. I know people can save their usernames and passwords on these in their web browsers.
I need to show / hide a label (<label></label>). if the field is empty then the label has to appear, if there is any value in the field then the label has to hide,
but this doesn't work with the browser autocomplete, is there anyway I can track this?
I tried with:
jQuery.change();
but that doesn't work.
Is there anything I can do about this rather than turning autocomplete off?

The norm here is to use the placeholder attribute on the relevant input element:
<input type="text" placeholder="username">
username will be displayed within the input when there's no text, and hidden otherwise. If you're using this, then you should probably also use something like Modernizr to detect support and create a normal text label otherwise.

You have to manually trigger the change event:
$("#username")
.change(function () {
// do stuff on change (check for default)
})
.trigger("change");
or use some watermark library if you only want to toggle default text (or the placeholder attribute with Modernizr as aviraldg recommends).

This is very simple.
I use this for my site's text fields.
This coding is in Javascript text.
create a <form> with name and id = "comform" (you can change this later; just for reference).
create an <input type = "text" with name and id = "Message" (you can change this later; just for reference).
create a <div> with id = "ifsend" (you can change this later; just for reference).
Also create a variable to store the length in. var numbering (you can change this later; just for reference).
function counter() {
var numbering;
numbering = document.forms["comform"]["Message"].value.length;
if (numbering == 0) {
label();
}
if (numbering != 0) {
document.getElementById('ifsend').innerHTML="";
}
}
function label() {
document.getElementById('ifsend').innerHTML="Your form value is empty";
}

Dynamically added a field in different forms using Jquery

I'd like to have a field that doesn't show at first, but if the user decided to input to it, then it will appear in the form.
I can use Jquery and do something like
$('input[example]')
.bind('click', function() {
$('#clickfield')
.append('<input id="new_field" name="MODEL[new_field]" size="30" type="text">');
However, I'd like to add this field in several different forms for different models.
Since the model name is in the field, how would I write the Jquery script to be modular so I can use the same script for all my forms?

One solution is to make a function with the names you want as input parameters:
addInput(form, id, modelName) {
$(form).append(
'<input id="'+id+'" name="'+modelName+'['+id+']" size="30" type="text">'
);
}
Where form would be the selector of the field ('#clickfield' in the example case), id would be the id of the new input field, and modelName would be the name of the model you mentioned.
Other solution, assuming 'input[example]' selects some button or clickable area that triggers the event of showing the field; and '#clickfield' is some div or span or some area where you will show your field, is to load these hidden fields from the server, styled as display:none, with a mnemonic class, so you could do something like define a function:
showField(clickable, class) {
$(clickable).click(
function(){
$(class).show();
}
);
}
and then:
$(document).ready(
showField('input[example1]', '.class1');
showField('input[example2]', '.class2');
showField('input[example3]', '.class3');
// .
// .
// .
// One line for every clickable area that triggers
// the event of showing a field, and the class of the
// field to show
);
this way you could add some user friendly features like fading the field in with the fadeIn() Jquery function (instead of show()), or any other animation on appearing.
Hope you could use it! good luck!
