How do I get the input element from within the directive before the template overwrites the contents?
html
<div xxx>
<input a="1" />
</div>
js
app.directive('xxx', function(){
return {
restrict: 'A',
template: '<p></p>',
replace: true, //if false, just leaves the parent div, still no input
compile: function(element, attrs) {
console.log(element);
return function (scope, iElement, iAttrs) {
}
}
};
});
i am on angular 1.0.x, I cannot pass in optional scope parameters with the '=?' syntax and i want to be able to override a portion of the default template of the directive in a very flexible way. instead of adding a scope variable or attribute everytime that I just plan on passing through the directive, I want to be able to supply the whole element to be used.
edit the input must retain the scope of the directive, and not the parent.
edit I am trying to include a partial template inside a directive that will overwrite a piece of the actual template. The piece I am including therefore needs to have access to the directive's scope and not the parent's.
Update It seems if I do not provide a template or a template URL and instead replace the contents manually using the $templateCache I can have access to the inner elements. I want to let angular handle the template and the replacement though and just want to be able to access the contents in the directive naturally before they get replaced.

html
<body ng-controller="MainCtrl">
<div editable="obj.email">
<input validate-email="error message" ng-model="obj.email" name="contactEmail" type="text" />
</div>
</body>
js
app.controller('MainCtrl', function($scope) {
$scope.obj = {
email: 'xxx'
};
});
app.directive('editable', function($log){
return {
restrict: 'A',
transclude: true,
template: '<div ng-show="localScopeVar">{{value}}<div ng-transclude></div></div>',
scope: {
value: '=editable'
},
link: function(scope) {
scope.localScopeVar = true;
}
};
});
app.directive('validateEmail', function($log){
return {
restrict: 'A',
require: 'ngModel',
scope: true,
link: function(scope, el, attrs, ctrl) {
console.log(attrs['validateEmail']);
}
};
});

The ng-transclude directive facilitates AngularJS to capture everything that is put inside the directive in the markup and use it somewhere in the directive's template.
In addition to all the built-in AngularJS directives, you can create your own directives. New directives are created by using the . directive function. To invoke the new directive, make an HTML element with the same tag name as the new directive.
The restrict option is typically set to: 'A' - only matches attribute name. 'E' - only matches element name. 'C' - only matches class name. 'M' - only matches comment.
The ng-click directive defines AngularJS code that will be executed when the element is being clicked.
I believe you're looking for the transclude function (link is to 1.0.8 docs). You can see what's going on with:
app.directive('xxx', function($log){
return {
restrict: 'A',
transclude: true,
compile: function(element, attrs, transclude) {
$log.info("every instance element:", element);
return function (scope, iElement, iAttrs) {
$log.info("this instance element:", element);
transclude(scope, function(clone){
$log.info("clone:", clone);
});
}
}
};
});
