推荐答案

您好，先生，
这很简单，但是您必须确保iframe内容页面(编辑器)和文本框页面(预览)在同一个域中.

1-在主页上创建一个Java脚本函数，以获取内容并将其放入文本字​​段
喜欢
函数fillText(text)
{
field = document.getElementById(''textFieldId'');
field.value =文本;
}
2-现在在编辑器窗口中处理事件(onkeypress)
可以说我们有一个全文编辑器的简单文本区域.
< textarea onkeypress ="parent.fillText(this.value)"></textarea>

希望这可以弄清楚:D

Hello Sir,
This is quite simple, but you must be sure that the iframe contents page(the editor) and your text box page(preview) are on the same domain.

1- Make a java script function in the main page which gets the content and puts it to the text field
like
function fillText(text)
{
field = document.getElementById(''textFieldId'');
field.value = text;
}
2- now handle the event (onkeypress) in the editor window
lets say we have a simple textarea insead of a full text editor
<textarea onkeypress="parent.fillText(this.value)"></textarea>

Hope this make things clear :D
