I want dynamically add text-box in html page when user is press a button. and after that i want to get the respective field value or all field value.
I tried doing ng-repeat but it will not work. can anyone tell me how i will achieve this.
I would indeed use ng-repeat, and just push a new object onto the array. Maybe something like this?
<button ng-click="textFields.push("")">Add</button>
<textarea ng-repeat="val in textFields" ng-model="val"></textarea>
Well there are a few things you could try. One of them is loading a hidden div when clicked on the button. The hidden div contains the text box.
Like this :
$(document).ready(function(){
$("#hiddendiv").hide();
$("#button").click(function(){
$("#zmedia").show();
}};
And in your html form you just add a div that contains a textbox and the id of the dive should be "hiddendiv". The downside is that once the hidden div is loaded, it cant be removed. There are other scripts that are a lot more sophisticated, check these links out:

Can someone help me out here on how to add passengers count dropdown form like on the image below. i have been searching all over but cannot seem to find any demo or help.
thanks for your help
This is a solution using pure HTML, CSS, and jQuery. For a Bootstrap-specific answer, How use input field as toggle for bootstrap 4 dropdown may help.
Moving on.
You should create a normal number type form and add a disabled attribute in the input tag so that no cursor appears when you click the form (<input type="number" disabled>). Then, just create a dropdown menu (probably a <div> with an absolute position right under the input) with a classname of your choice (assuming in this answer that you choose .passengerInput as the classname).
You can hide the dropdown by default using the $(".passengerInputDropdown").hide() method in the body of your JS.
Then, when you click the form, using the $(".passengerInput").toggle() method, do something to the effect of:
$(".passengerInput").on("click", () => {
$(".passengerInputDropdown").toggle();
})
Let me know if this helps!
I want to track clicks on the following button/link with Google Tag Manager. I created a trigger in Google Tag Manager that triggers when the element_id = 100. This works fine, except that when I click exactly on the text, it doesn't do anything, the link looks like a button, with the text in the middle of it. I can't change anything to the html or css, otherwise I can think of multiple things, so I need to find a solution without changing the html. Also, the 'myclass' class and the 'label' class get used in other elements.
<a class="myclass" id="100" href="http://www.url.com">
<span class="label">Text</span>
</a>
Anyone an idea?
Thanks a lot,
The following workaround worked:
Create trigger when element text contains "Text". This will trigger events on the button and the label on the button, of all buttons with "Text" as label.
Create tag for that trigger that checks with simple javascript if either the id of the current element = 100, which will happen when you click the button but not the label, or that the id of the parent = 100, which happens when you click the label. You can get the element that triggered the tag using the built-in variable "Click Element". Which you need to access the parent element.
Technically, you shouldn't have a CSS ID that starts with (or is) a number, so not sure if your code example is accurate or not. Whatever the case, you're probably better off using "matches CSS selector" so that you don't need to use any custom JS.
If indeed your HTML uses id="100", then the above will work. If it's anything else that doesn't start with a number, then you can use
#whatever > span
In my AngularJS project I have an account details page where you can change your personal account information. This page allows for multiple phone numbers and e-mailaddresses to be supplied. Using mouse input (or tabbing to buttons and pressing them with space bar) works perfectly, however I'd like to add the convenience of the enter key pressing the 'logical' buttons.
My form looks like (accidentally forgot to translate a few items):
A simplified version of the HTML for the form can be found on PasteBin, I've mainly removed the directives for managing the lists.
All buttons are <button> elements except for the cancel button which an <a> to the previous page, and the submit button is <button type="submit">.
When selecting any text box and pressing enter, the first (non-disabled) <button> element is 'clicked'. Meaning if I would change the last name, hit enter, the first phone number would be removed.
When you're in a new entry of phone numbers or e-mailaddresses (the row with the green + button) it should click that button, and if it's disabled do nothing.
When you're in any other text box on the form it should hit the save button, and also if the save button's disabled, do nothing.
Both buttons will be disabled based on form validation.
There'd be no trouble in changing the type of a button from button to submit if that'd help.
I would preferably have an all HTML solution, using just semantics, but I doubt that's really possible. So the logical alternative would be to use an AngularJS directive.
Please do not provide a jQuery or plain JavaScript solution relying on IDs or something like that. I don't want to hack my way around AngularJS, rather embrace it.
In the meantime I've worked on a directive that allows me to declare what I've called 'submit scopes'.
In essence you have actions (inputs) and targets (buttons), they're bound through a service by a key you can assign in the template. To avoid keys from clashing and from simple annoying work you can create a submit-scope which will cause it's children to prepend a unique key to the value they're accessing.
Within a submit-scope you can still override an action to use a global key instead by setting the attribute global-submit="true".
Example code:
<div submit-scope>
<input type="text" submit-action />
<button type="button" submit-target>Pressing enter in the above field will click this button.</button>
</div>
You can view the entire source code and a slightly larger example on Plnkr.
I just tried to replace
<button>Cancel</button>
with
<input type="button" value="Cancel">
and it seems to work correctly...
I'm writing a veeeeeeeery simple code where a Spark TextArea is in a TabNavigator and I want to write something into it dynamically. The problem is: when I try to do it the TextArea stays white until clicking on it makes the text appear magically.
The mxml is this:
http://pastebin.com/7WqvXuH2
and very simple code to write is this:
xmlError.text += error+"\n\n";
I also tried this but with the same result
xmlError.appendText(error+"\n\n");
Hope I've been clear.
As a work-around I've used the code below, there are multiple input fields on this view setting the focus on just one of the text inputs causes all of them to render the text correctly.
The only really relevant "property" is the creationComplete handler.
<s:TextInput autoCapitalize="none"
autoCorrect="false"
creationComplete="{tiFirst.setFocus()}"
id="tiFirst"
prompt="{data.firstName}"
text="{data.firstName}"
width="300"
tabIndex="0"/>
I would like to create a form that changes dynamically.
I have a form for creating a project (with fields such as: project_name, project_description...) and the project can have any amount (bigger or equal to 0) of categories.
What i want is to display a button which would give the user the option to add another category field. In addition I would also like the option for category fields to be "deleteable" by the user (if he changes his mind or made a mistake). What would be the best way to do so. I would like an Ajax type solution.
My solution so far is to leave an empty div beneath the last category and onclick of the button to load another field into that div with yet another div which will be used for the next div. Not to happy with this solution since i now have to count how many fields I have and give each div it's own id which complicates the matter even more.
Is there a more simple solution to this?
If you are trying to add fields dynamically with a button, you can easily do so by doing something like the following:
HTML:
<form>
<p>
<label>Name:</label> <input type="text">
<label>Age:</label> <input type="text">
<span class="remove">Remove</span>
</p>
<p>
<span class="add">Add fields</span>
</p>
</form>
JS:
$(".add").click(function() {
$("form > p:first-child").clone(true).insertBefore("form > p:last-child");
return false;
});
$(".remove").click(function() {
$(this).parent().remove();
});

I started to write a form generator is based on a definition in JSON a while back. It works but could use some enhancements. It's written using Prototype.js but it wouldn't be a huge effort to port it over to jQuery.
You're welcome to steal the code. (just view source)
I've done something similar. To delete fields I didn't really removed fields. I just hidden them with a display:none and had a hidden input "delete" that I trigger to true. Then, the page receiving the result knows which field is to be deleted in the database.
They are not deleted before the form is submitted. It's like a "two pass" conception. But if you don't really need a true ajax, it works fine. Otherwise you need your JS remove function to call the server and tell to delete the field with its id. A little bit more complex to code.
