I have a listbox in an Adobe Acrobat form. When I change the value of the listbox, the source of the image field has to be changed with a javascript script:
As a first step, I tried to change the src in javascript, so not yet with the listbox:
var logo = this.getField("companylogo"); // button field
logo.buttonImportIcon("C:\Users\VincentJanssens\Downloads\Blauw.png")
But even this code isn't working.
Thank you for getting me started!
The code can be very simple if you set the fields up to allow for that. The first step is to create buttons for each of the images you want to be available. Name these buttons such that the Export Value of the item in the Dropdown matches exactly. Set these buttons to Hidden and Read Only in the General tab.
Then add a button where you want the various images to appear on your form. Set this field to read-only too. Now, set up the Dropdown to Commit the selected value immediately and add the following JavaScript to the Format script of the dropdown. Replace the string 'displayImage' with the name of the button field you placed on your form.
this.getField("displayImage").buttonSetIcon(this.getField(event.target.value).buttonGetIcon())
Now each time the list item changes, the script will run and use the Export Value of the field to get the button icon from the button with the same name as the export value.
I've posted a working example file here.

Introduction:
I have a reactiveform. It contains two form fields named name and value. So I have a add button which duplicates the form. So if I click it the form fields name and value duplicates. So I am trying to use the respective inputs of the formfield named value below. I assign it to (I mean the one in html)formvalues below the form field. So when I enter the input(lets say 1) of the value formfield in the first form, the formvalues variable below gets updated to that input(1) entered. So now If I duplicate the form and enter another input(lets say 2) in that value formfield. Now the formvalues gets extra value 1,2.
Myproblem:
In real time I have a popup button in each set of reactiveforms. So In that popup the input of the particular value formfield appears. So if I duplicate and enter another input in the value formfield and now I click the respective popup of that particular form then the input of the respective value formfield(duplicated one) should be present. But now what a happens is that all the values present in the respective value formfield appears as (Example: 1,4,6,7).
I dont know whats the real issue here so Forgive me if my question title was misleading. Please comment below if my explanation was unclear.

Note: Most part of the above code link was done by user #VimalPatel here in stackoverflow.I am giving him full credit for the code written in that link
I couldnt install boostrap in that sandbox code, so instead of that I have made a show button instead of popup to show the values I am getting.
Create a variable of type FormGroup as your form contains a FormArray. It will hold the currently selected form. In your button click pass the current form as argument to your show method.
<button (click)="openForm(form)">Show</button>
openForm(form: FormGroup) {
this.selectedFormGroup = form;
}
In your template you get show the selected form value like this.
<div *ngIf="selectedFormGroup">
{{selectedFormGroup.value | json}}
</div>

----SOLVED----
I'm creating a textbox in Angular/Ionic that has prefilled text from the previous page.
I have a Notes page that comes right before the current page, and asks the user to document any notes they'd like.
On the current page, I want there to be a notes box with the notes that the user last entered. From here, the user should be able to edit these notes if necessary. I've created two separate notes pages because this last page acts as a summary page before the user submits the data to the server.
I've already tried using the placeholder option, where I set the placeholder to the notes the user enters on the first screen, but all of that data disappears as soon as the user touches the box again. I want the text to still be there and editable.
I also tried putting the notes inside of , but that is not editable.
<div class="notesBox">
<ion-textarea id="prefill" [(ngModel)]="notes" (ionChange)="updateNotes()"></ion-textarea>
</div>
this.prefilledNotes = this.dataService.getNotes();
(<HTMLInputElement>document.getElementById("prefill")).placeholder = this.prefilledNotes;
Try:
(<HTMLInputElement>document.getElementById("prefill")).value = this.prefilledNotes;
You can create a service which has a variable for notes and instead of manipulating data using document.getElementById you can directly get and set that variable wherever you need
The solution is to use [(ngModel)].
<div class="notesBox">
<ion-textarea id="prefill" [(ngModel)]="prefilledNotes" (ionChange)="updateNotes()"></ion-textarea>
</div>
this.prefilledNotes = this.dataService.getNotes();
By first setting the ngModel property value to whatever the user already entered, it populates the textbox with that value. It also is editable.
I'm learning javascript right now (using firebug console of browser) and have trouble understanding how to activate changes when I enter a command.
For example, one website has a dropdown box name "mvprodvaronetimeorder" with several options like:
IpA-Q-Q, IpQ-Q-Q, Ipw-Q-Q... I can use the command to get to the 3rd value:
document.getElementsByName("mvprodvaronetimeorder")[0].value="Ipg-Q-Q";
However, it doesn't activate the same action when I choose the corresponding value from dropdown box (display another dropdown to choose). Then I cant interact with 2nd dropdown box and other things after that.
Same thing happens when I try to fill a text box using command like:
document.getElementById("luckyme")[0].value="You are lucky";
While it change but the change doesnt reflect when I click the submit button, it require me to copy paste or type of at least click to that textbox to activate changes.
Is there anyone can suggest me how to automated the process from console?
Assigning the value in JavaScript updates the selection, but it doesn't notify the code running on that page of the change.
To make the page react to the change you also need to trigger a change event on the dropdown:
var el = document.getElementsByName("mvprodvaronetimeorder")[0];
el.value = "Ipg-Q-Q"
el.dispatchEvent(new Event("change"))
The page then knows the selection has changed and it shows the new dropdown below.
To find out what events an element is listening to you can use getEventListeners:
getEventListeners(document.getElementsByName("mvprodvaronetimeorder")[0])
// Object {change: Array[1]}
Aspx page :
fileupload
dropdownlist subject
Textarea
User can write anything in textarea.There is no sequence, that user can first write text or upload file.Dropdownlist has onchange and selected indexchanged event.Onchange event calling javascript function which convert '<',to it's html encode character if textarea contain.On selectedindex change appropriate script of that subject code get added into textarea replacing previous one.It is not necessary that user should select subject for script,can write it's own.Every thing is working properly over here.When I selecting file other than text I want hide dropdownlist subject and want to make index at zero.
Suppose I uploaded text file,selected subject which inserted script into textarea,now I want to select img rather than text file,if I do, dropdownlist get disable and show first value document.getElementById('ddlSubject').selectedIndex = 0.Textarea is empty.Every thing is working properly here .But when I again select textfile,textarea and dropdownlist get enable.If I choose one subject which was selected previously,serverside event of dropdownlist did not get fired.If I choose other subject it call server side function.How to handle this
Please make sure you have the property of the control set as AutoPostBack = true. Furthermore, it'll be easier if you could share a code snippet.
I'm having trouble finding javascript, HTML and/or CSS code that'll change the form based on the drop down menu. For example, the form is for adding a property and the drop down menu selections are single family, condo, apartment but they each have their own set of text boxes, menus and radio buttons. How can I achieve this?
What I have understand from your query is that , you have a from with some fields and you have a dropdown and you want that when ever your change selection in dropdown the form fields values must change accordingly right ?
If that is the issue , then it is very simple , first catch onSelectionChange event of dropdown and try to get selected value and once you get the selected value fill form fields by accessing them accordingly in a condition.Thanks
So I actually already had a piece of code I was fumbling with (http://jsfiddle.net/CYzsY/) for this question and it looks like its not working for me because its based on jQuery 1.7.1 and I'm linking to 1.10.2 in my code. Will make a new post accordingly. Thanks everyone!
