如何獲取iframe的documentElement

Question

當我運行此代碼時，它不起作用

goruncode(){
    editor = ace.edit('editor');
    var editorvaluet=editor.getValue();
    frames['screen'].document.documentElement.innerHTML = editorvaluet;" 
}

和HTML

I have a <iframe id="screen"></iframe>

所以當我單擊更新時它不會更新

Answer 1

采用

document.getElementById("screen").contentDocument.documentElement.innerHTML
