I have an AngularJS directive in which I want to add a svg tag to the current element of the directive. Right now I do this with the help of jQuery
link: function (scope, iElement, iAttrs) {
var svgTag = $('<svg width="600" height="100" class="svg"></svg>');
$(svgTag).appendTo(iElement[0]);
...
}
Yet I don't want the directive to depend on jQuery for this simple task. How would I accomplish the same with AngularJS means (or native JavaScript code).
Why not to try simple (but powerful) html() method:
iElement.html('<svg width="600" height="100" class="svg"></svg>');
Or append as an alternative:
iElement.append('<svg width="600" height="100" class="svg"></svg>');
And , of course , more cleaner way:
var svg = angular.element('<svg width="600" height="100" class="svg"></svg>');
iElement.append(svg);
$compile : docs.angularjs.org/api/ng/service/$compileIn angularJS, you can use angular.element which is the lite version of jQuery. You can do pretty much everything with it, so you don't need to include jQuery.
So basically, you can rewrite your code to something like this:
link: function (scope, iElement, iAttrs) {
var svgTag = angular.element('<svg width="600" height="100" class="svg"></svg>');
angular.element(svgTag).appendTo(iElement[0]);
//...
}
angular.element(svgTag).prependTo(iElement[0]);. Thanks @nXqdYou could use something like this
var el = document.createElement("svg");
el.style.width="600px";
el.style.height="100px";
....
iElement[0].appendChild(el)
If your destination element is empty and will only contain the <svg> tag you could consider using ng-bind-html as follow :
Declare your HTML tag in the directive scope variable
link: function (scope, iElement, iAttrs) {
scope.svgTag = '<svg width="600" height="100" class="svg"></svg>';
...
}
Then, in your directive template, just add the proper attribute at the exact place you want to append the svg tag :
<!-- start of directive template code -->
...
<!-- end of directive template code -->
<div ng-bind-html="svgTag"></div>
Don't forget to include ngSanitize to allow ng-bind-html to automatically parse the HTML string to trusted HTML and avoid insecure code injection warnings.
See official documentation for more details.
