Incorporating angularjs into my project, I am faced with the challenge of dynamically populating a form and then submitting the data via POST to a server.
Initially, I set up a data variable in my controller for the purpose of later POSTing it:
$scope.data = {};
Subsequently, in my HTML file, I proceeded to generate the form elements using the following code snippet:
<div ng-repeat="(name, attributes) in fields">
<element myVar="data.{{name}}" name="{{name}}" attributes="{{attributes}}" ></element>
</div>
The 'fields' variable contains information about how each field should be displayed, as shown below:
{"agency":{"name_displayed":"Agency","size":"30","tag":"input","type":"text"},"department":{"name_displayed":"Department","size":"30","tag":"input","type":"text"},"description":{"cols":"50","name_displayed":"Description","rows":"4","tag":"textarea"}}
However, when implementing the element directive, I encountered several errors. The directive is outlined as follows:
demoApp.directive("element", function() {
var template = function(name, attributes, results) {
// Template generation logic
};
return {
restrict: "E",
scope: {
myVar: '='
},
link: function(scope, element, attrs) {
// Linking logic
}
};
});
The issue arises from the inclusion of the 'myVar' attribute and scope object within the directive code. Without these components, the form displays correctly. Am I overlooking something concerning two-way data binding? Is there an alternative approach I could take? - Appreciate any guidance.
