Same form for creating and editing data Angular4

阅读更多关于 Same form for creating and editing data Angular4

问题 Here is a form with two way-binded input fields. The goal was to create the same form to edit and create data. That was accomplished, but I am pretty sure that there could be a better way to do this (like using AbstractControl features). I also miss one fix here - if clickEdit() being clicked need to update form values with that object which user wants to edit. Thanks for any help and especially explanations about AbstractControl and NgModel .. <div> <form (ngSubmit)="clicked ? onEditSubmit(

Angular - ng-change not firing when ng-model is changed

阅读更多关于 Angular - ng-change not firing when ng-model is changed

问题 The input is the following: <input type="text" ng-model="repair.test" ng-change="action()" /> The action() is executed when I manually type and change the input. However if I change the repair.test value by some other function programmatically, it doesnt fire the ng-change's action.

What is the purpose of the new built in 'parse' validation key in Angular 1.3?

I now always see a new validation key named 'parse' added to all $error objects, and whenever one of the parsers returns undefined, it overrides/replaces all other validation keys that may have been already set. For instance, here is a working example in Angular 1.2.23 - try entering a number out of range: http://jsfiddle.net/8doq0saf/5/ The same thing running under 1.3-rc gives a

How can I make angularjs ngChange handler be called only when user finishes typing

阅读更多关于 How can I make angularjs ngChange handler be called only when user finishes typing

问题 I have an input field, where I want to apply the variant of ngChange . The input field is sort of binding with an ajax call, when user changes the input, the server side will process the data, however, I don't wanna make the call too often. Say the user wanna input a really string, I want the call be made only after user finishes the word he is about to type. Nevertheless, I don't wanna use event such as blur. What would be a better way to implement this, rather than setTimeout ? 回答1: Use ng

问题 I have an array of tranTypes (transaction types) that are loaded into a dropdown. After the user selects a value and navigates to another component upon returning the value is not selected in the dropdown. From other readings, I've learned this is b/c the objects are not the same instance.
