I get HTML configuration data from a json file. When that has loaded, I need to make sure that the document is ready before plugging the HTML into existing elements.
var cfg;
function getJSONconfigdata() {
$.getJSON("/quizdata.json", function (json) {
cfg = json;
//Now do everything else
init();
});
}
getJSONconfigdata()
function init(){
//Plug cfg values into existing dom elements. but they may not exist yet.
//...
}
init() is called after the json file has been parsed, but how do I make sure the dom is also ready? I have tried $(function (){ init(); }); but cant make it work - it seems to fire before json is loaded.
Yes, the $(document).ready()
runs when the DOM is prepared for JS. When many people use jQuery they will put all of their code that will interact with page elements within the $(document).ready()
statement to ensure that. So
$( document ).ready(function() {
var cfg;
function getJSONconfigdata() {
$.getJSON("/quizdata.json", function (json) {
cfg = json;
//Now do everything else
init();
});
}
getJSONconfigdata()
});
