Warten Sie auf Element JavaScript

var checkExist = setInterval(function() {
   if ($('#the-canvas').length) {
      console.log("Exists!");
      clearInterval(checkExist);
   }
}, 100); // check every 100ms

JavaScript warte auf DOM

document.addEventListener("DOMContentLoaded", function(event) { 
  //do work
});

JavaScript wartet auf Element

let observer = new MutationObserver((mutations) => {
  mutations.forEach((mutation) => {
    if (!mutation.addedNodes) return

    for (let i = 0; i < mutation.addedNodes.length; i++) {
      // do things to your newly added nodes here
      let node = mutation.addedNodes[i]
    }
  })
})

observer.observe(document.body, {
    childList: true
  , subtree: true
  , attributes: false
  , characterData: false
})

// stop watching using:
observer.disconnect()

So wartet ich auf DOM in JavaScript

function bindReady(){
    if ( readyBound ) return;
    readyBound = true;

    // Mozilla, Opera and webkit nightlies currently support this event
    if ( document.addEventListener ) {
        // Use the handy event callback
        document.addEventListener( "DOMContentLoaded", function(){
            document.removeEventListener( "DOMContentLoaded", arguments.callee, false );
            jQuery.ready();
        }, false );

    // If IE event model is used
    } else if ( document.attachEvent ) {
        // ensure firing before onload,
        // maybe late but safe also for iframes
        document.attachEvent("onreadystatechange", function(){
            if ( document.readyState === "complete" ) {
                document.detachEvent( "onreadystatechange", arguments.callee );
                jQuery.ready();
            }
        });

        // If IE and not an iframe
        // continually check to see if the document is ready
        if ( document.documentElement.doScroll && window == window.top ) (function(){
            if ( jQuery.isReady ) return;

            try {
                // If IE is used, use the trick by Diego Perini
                // http://javascript.nwbox.com/IEContentLoaded/
                document.documentElement.doScroll("left");
            } catch( error ) {
                setTimeout( arguments.callee, 0 );
                return;
            }

            // and execute any waiting functions
            jQuery.ready();
        })();
    }

    // A fallback to window.onload, that will always work
    jQuery.event.add( window, "load", jQuery.ready );
}
