还有一个关于textbox的问题
如果我设置 textmode 为 password当我调用函数 设置 textbox1.text = "xxx"时
文本框的显示却是空白，如果在其他函数 读取 textbox1.text读到的就是空
我要怎么设置，才能让我读取的可以显示在文本框中 并以 ******的形式显示呢？ --------------------编程问答-------------------- LZ 你开玩笑了 我刚试了一下可以的 --------------------编程问答-------------------- textbox1.attribute.add("text","123456") --------------------编程问答--------------------
真的不行

你试试这个代码 --------------------编程问答-------------------- 或者textbox1.attribute["text"] = "123456"
没环境，手写，应该是这么拼 --------------------编程问答-------------------- <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
window.onload = function () {
var a = $("#TextBox1").val("123");
alert(a.val());
}
</script>
我把代码复制给你了
密码框里三个黑点,并且弹出信息框 显示123 --------------------编程问答--------------------
但是我还要可以输入，从里面读取东西出来啊，这样设置的话··输入之后读取还要另外写·· --------------------编程问答--------------------
这个要放在哪里啊？ --------------------编程问答-------------------- <head></head>里啊 --------------------编程问答--------------------
试过无效 --------------------编程问答--------------------
Microsoft JScript 运行时错误: “$”未定义
会提示这个啊·· --------------------编程问答-------------------- 你没有引用jQuery类库 --------------------编程问答--------------------
那换这个
<script type="text/javascript">
window.onload = function () {
var a = document.getElementById("TextBox1");
a.value = "123";
alert(a.value);
}
</script>
一样的意思 --------------------编程问答--------------------
Microsoft JScript 运行时错误: 无法设置属性“value”的值: 对象为 null 或未定义
囧了···
--------------------编程问答--------------------
--------------------编程问答--------------------
无语了,我机子上没一点问题,看看ID写对没有....... --------------------编程问答--------------------
依旧还是那样··无奈啊··
--------------------编程问答-------------------- 我也是这个问题！！
补充：.NET技术 , ASP.NET
