  • 同一页面的不同Iframe获取数据

    公共父页面(主页面):

                    var testVal = $("#testId").val();
                    window.parent.document.getElementById("test").value = testVal;
                })
            </script>
      </body>
    </html>

    效果图:

    1、页面刚加载时(a页面获取到b页面文本框内的值):

    2、页面加载完毕后(将b页面文本框的值赋值给父页面)
