I have a page on which there is a Modal registration, I have to call this modal from an external page, preferably by url, I would like to know if it is possible and if you can show me the way

OBS: THE Modal cannot be enabled directly on the page, and this page uses the Bootstrap to generate the Modai's.

javascript url

  • This external URL will be entered by someone else remotely?

  • Can you explain "call this modal from an external page"? so the page has the possibility to display a modal but only does it if the URL asks it? type Query string? minhapagina.html?modal=true -> opens and minhapagina.html -> won’t open?

  • is an external link, it passes a method GET and with it show the modal

  • So you want to read the querystring in JS to see if the modal should open? That’s it?

  • @Yes, yes, that’s right

  • ok, I’ll give you an answer but you can give one more indication: what does that url look like when you should call the modal? has some key to the modal?

To read the query string (GET) in a URL you can make a function like this:

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

In this case if you have a url minhapagina.html?modal=true then getParameterByName('modal) give away true.

This function I went to get from Soen but you may not even need something like this, if the url that activates the modal has no key/value pairs and only ?modal or nothing; then a .indexOf() suffice.

In this case you can use location.search.indexOf('modal') != -1 that will give real (true) if the word "modal" exists in ?xxxx of the url.
