Just want to ask a simple question since I am new to angularjs and html5.
I have written a directive to check if user has permission for a certain thing. Permissions are all an array of strings. Using directive I am hiding or showing a UI element if user has permission for that. For example if user doesn't have permission for editing a user, I would hide the edit button with the help of directive as follows;
div that contains edit button
<div has-restriction="UserEditNotAllowed"><button>Edit User</button></div>
My question is instead of typing in string "UserEditNotAllowed", is there a way so that while typing it, using intellisence I can see permission strings that are available to avoid typos.
I tried adding these permission string in $rootScope but intellisense doesn't show that. I am using webstorm.
Thanks,
Imad.
Firstly you don't have to use your own directive for hiding stuff based on app logic. Instead you could use ng-show.
<div ng-show="userAllowed"><button>Edit user</button></div>
Then inside your controller, set $scope.userAllowed = true; whenever you want the button to become visible.
As for intellisense, that is an entire other question which should be aimed at webstorm.

Hi my angular form is getting hanged when am try to scroll up and down and try to select drop down options, selecting items in list control. My form contains input controls which has regex patterns, controls. All these controls are in my child html form.
And if i clear cache its working fine.
Please suggest me to fix this issue.
Calling a method function from direct html can be costlier Operation which might have called your application function multiple times apart of life cycle hooks.
It's better to use always variable instead of functions if you are not using it already. Please share your code snippet or stackblitz url for better help from community
I have an input type number inside an Ionic v4 alert, the problem is that I can't set step property since It's not recognised, is there any workaround or solution?
If you have advanced alert needs you might consider making a modal form instead.
The alert doesn't have many configuration options.
I don't see the value in trying to recreate a full modal tutorial here. This seems to cover it quite well.
But the high level overview is that instead of using an alert you create what is basically a new page, but it is loaded in on top of the existing page and you can pass data in and out of it.
I've already asked a similar question, but I really can't figure out how to connect these elements together. I'm still not very good with Handlers, and I guess my question is:
How can I access UI Widgets (and their children) while outside of the doGet() function?
My use case is this: I have a list of projects/IDs. I have all the data I want based on the ID that will populate the Project Details tab of this application. I created 'unique' Buttons for each of these Projects, and threw them into a Grid. Now, I want to generate the Project Details (detailPanel) Widgets specifically for each Button if/when it is clicked.
I have the Project ID attached to each Button (uniquely) through a Hidden, but I can't seem to attach the Project Details tab (detailPanel) to the Button so that, when clicked, I can set the values for the TextBox, DateBox, ListBox, etc. Widgets of the detailPanel.
I think I'm missing something obvious about this. I want to avoid attaching each child Widget of the detailPanel as a callbackElement of the Button at all costs. There are around 40 elements (I've lost count), and it seems really inefficient. I'm almost sure that if I can add one Widget as a callback element, that I get access to all child Widgets. But I tried, and that doesn't seem to be the case.
Here is the link to the public UiApp, which shows the UI. And the sister Script Project (uneditable).
You dont need to add callback elements that you will write to, callback elements are only for reading their data. If the detailspanel id is dynamic have a hidden that has its id stored inside and pass it to the handler. from your handler you getelementbyid and set its data.
I was looking at the raw HTML rendered by a SharePoint (2010) list item edit page, and I noticed that an input field (rich text field) made use of an AlwaysEnableSilent attribute. i have checked online for an explanation of what the attribute does, but have not been able to get a answer. Does anyone know what this attribute does?
Thanks, MagicAndi
ASP.Net validators allow you to turn them on/off using client side scripting using ValidatorEnable, but whenever you turn the validator on that way the validation fires immediately. Sometimes you (SharePoint) may want to be able to control which validators are active using client side scripting, but without the validation firing when you turn it on (during load, before the users have had the possiblity to fill out the fields).
In order to handle this SharePoint has defined its own function STSValidatorEnable with an extra parameter bSilent, so it can turn on validators without them firing.
They then found out that for some validators they always want them not to fire when STSValidatorEnable is called, even though the caller uses bSilent==false. So they introduced an attribute AlwaysEnableSilent which tells the validator never to fire when turned on using STSValidatorEnable, but only during postback.
I am in a predicament with input files. The project I am working on has added a jQuery extension that masks all input types and makes them more 'vibrant'. However it has also caused a lot of trouble in the updating of what is listed in these inputs. One such problem is the input with type file. It currently will not change what is being uploaded after the very first selection. So I am wondering if there is a command you can use to do something after the user has selected a file (pressed the Open) button.
I'm not exactly positive on what you're asking for but: you can bind logic to the input's onchange event. This will run the code attached to it after the user has selected their file(s) and pressed the "Open" or "Cancel" buttons.
Here's an example using jQuery (since you've already stated you're using it):
$("#yourFileInput").change( function() {
alert("Hey, you changed me!");
});
