Question

任何人都可以在ACE编辑器(https://ace.c9.io/#nav=api&api=editor)中使用简单的getValue()进行更改事件时,如何进行更改事件.并将新文本发送到div？非常感谢,因为没有关于如何使用Ace Editor以及文档的教程.谢谢

请参阅 https://jsfiddle.net/ralf_htp/hbxhgdr1/和http://jsfiddle.net/revathskumar/rY37e/

HTML

<div class="container">
  <div class="panel panel-default">
    <div class="panel-heading">
      <h3 class="panel-title">Editor</h3>
    </div>
    <div class="panel-body">
      <a href="#" onclick="update()">go</a>
      <div id="editor" onChange="update()">function foo(items) { var x = "All this is syntax highlighted"; return x; }
      </div>
    </div>
  </div>
  <div id="output">Output is here (click 'go' and write HTML and js in the editor) </div>
  <div class="text-center">---End of editor---</div>
</div>

JavaScript的

var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.getSession().setMode("ace/mode/javascript");
editor.getSession().on('change', function() {
  update()
});

function update() //writes in <div> with id=output
{
  var val = editor.getSession().getValue();
  var divecho = document.getElementById("output");
  divecho.innerHTML = val;
}

函数update()实现与编辑器关联的onChange事件.如果单击go-link然后在编辑器中写入一个字符,则update() - 函数输出update()with 中的编辑器内容onChange为html(innerHTML)

CSS

#editor {
  /** Setting height is also important, otherwise editor wont showup**/
  height: 300px;
}

#output {
  height: 100px;
}
