Suppose your text field's id is myTextField, whatever you named it. if it has no id, set a id for it. then, in the popup window, you can use JavaScript parent.document.getElementById('myTextField').valueto get the value of the textfield.
假设您的文本字段的 id 是myTextField，无论您如何命名它。如果它没有 id，则为其设置一个 id。然后，在弹出窗口中，您可以使用 JavaScriptparent.document.getElementById('myTextField').value获取文本字段的值。

Assign window.open()to a variable so you can access it's elements.
分配window.open()给一个变量，以便您可以访问它的元素。
<form>
<input type="textbox" id="txt" />
<input type="button" id="btn" value="Open window" />
</form>
<script>
document.getElementById('btn').onclick = function(){
var myWindow = window.open();
myWindow.document.body.innerHTML = document.getElementById('txt').value;
};
</script>
