Any of those help I have a simple button and a directive I want to access the button's style, add MarginLeft with an onclick() function in the directive it is not working but setting the css from constructor works how can I use this with on click? please help: , You could use a HostListener in your directive:
code :
@HostListener('click') onClick(){
    this.element.nativeElement.style.marginLeft=20;
    console.log("marzi"+this.element.nativeElement.style.marginLeft);
}

angular built-in directive is not working after custom checkbox directive (with isolate scope) added

angular built-in directive is not working after custom checkbox directive (with isolate scope) added

I wish this help you I am trying to create a custom checkbox directive in Angular, and I have managed to do so. but the problem is that the build-in ng-click is not called. if the custom directive is removed, the ng-click works well. I guess it is something to do with Scope, which I am still lacking knowledge to figure out. can anybody help me please. , That's because you have a directive with an isolated scope try this:
code :
<div checkbox="p.checked" ng-click="$parent.test()">test</div>

Hope this helps Relying on arbitrary function from directive's scope doesn't look like 'totally encapsulated', more like the opposite of it. And btw, you can't do that anyway.
Standard Angular approach is something like this
code :
app.directive('myDirective', function () {
  return {
    scope: true,
    transclude: true,
    template: '<div ng-transclude ng-mousemove="go()"></div>',
    link: function (scope){
      scope.go = function () { ... };
    }
  };
});

around this issue Angular modules are not hierarchical.
Registering your directive in your root AppModule only tells Angular that the AppModule uses the declared directive. You'll still need to import it into whichever module you want to use the directive.

seems to work fine One approach to adding directives to templates based on component attributes is to use the function form of the template property:
code :
<my-custom-directive data-placeholder="No text"
                     model="vm.data" 
                     custom="not-editable-directive-attribute" >
</my-custom-directive>
app.directive("myCustomDirective", function() {
    return {
        template: createTemplate,
        scope: {},
        //...
    });
    function createTemplate(tElem, tAttrs) {
        var placeholder = tAttrs.placeholder;
        var model = tAttrs.model;
        var custom = tAttrs.custom;
        return `
            <input placeholder=${placeholder}
                   ng-model=${model}
                   ${custom} />
        `;
    }
})
