Is possible to add a <meta> tag for my Lightning application?
Within the Salesforce1 mobile application my iPhone turns a custom-formatted date visualization into a hyperlink to create a native calendar entry. As described here you can prevent this by adding
<meta name="format-detection" content="date=no">
to your webpage, but as I don't have access to the generated HTML <head>-section directly is there another way defining this within a Lightning Component?
you can get the response here
Two Options
1.-
If you are building a Community, You can Add it from
All Communities -> Builder -> Settings -> Advanced -> Edit Head Markup
2.-
If you are building a Standard Lightning APP, You can Add it from Javascript, but you dont need to use JQuery (I think is your problem).
In a Lightning App you have the following (App Component)
> <aura:application template="c:test_empty_template">
>
> <aura:handler name="init" value="{!this}" action="{!c.doInit}" /> <header class="tlf-header">
> <div class="tlf-header__top"> ...
(App Controller)
> ({
> doInit : function(component, event, helper) {
> var meta = document.createElement("meta");
> meta.setAttribute("name", "format-detection");
> meta.setAttribute("content", "date=no");
> document.getElementsByTagName('head')[0].appendChild(meta);
>
> } })
And viewport is injected in the application Head
Update - this answer is about adding meta to Visualforce pages, not lightning components as originally asked
This seems to be a limitiation in Visualforce and Apex. Disclosure: I'm new to VF / Apex but very experienced in HTML. There are Apex-approved ways of adding scripts and stylesheets to the head of a document with the <apex:includeScript /> and <apex:stylesheet /> tags.
But there's no equivalent for adding meta as far as I know.
You can, as a type of hack, insert the <meta ... > at the top of the VF page and it may work. I've done a similar quick workaround with the <meta viewport...> element for responsive pages on mobile devices, and it works.
However, this is technically invalid markup.
