使用Javascript设置表单 [英] Setting forms using Javascript

问题描述

大家好，


学习Javascript（通过谷歌）创建具有预设值的表格。

如下所示。我发现的问题是：我似乎无法弄清楚

（或通过谷歌找到目前为止）如何在输入类型时预设表格选项

是单选按钮或下拉列表。使用输入字段时，同样的方法似乎不起作用

。


任何人都知道这么全面的网站吗？


非常感谢，


Daniel


< FORM name =" PersProf"行动= QUOT; newuser.pl" method =" POST">


< table border =" 0">

< tr>

< td WIDTH =" 200">

名字

< / td>

< td>

< input type =" text"名称= QUOT;如first_name" maxlength = 32 size = 32>

< / td>

< / tr>

< / table>

< script language =" JavaScript">

<！ -

//设置值：

document.PersProf.first_name.value =''$ first_name'';

- >

< / script>

Hi All,

Been learning Javascript (via google) to create forms with pre-set values.
As seen below. My problem I have found is this: I can''t seem to figure out
(or find so far via google) how to preset form options when the input type
is a radio button, or dropdown list. The same method does not seem to work
with input fields.

Anyone know of such a comprehensive site?

Thanks ahead,

Daniel

<FORM name="PersProf" action="newuser.pl" method="POST">

<table border="0">
<tr>
<td WIDTH="200">
First Name
</td>
<td>
<input type="text" name="first_name" maxlength=32 size = 32>
</td>
</tr>
</table>
<script language="JavaScript">
<!--
//setting the value:
document.PersProf.first_name.value = ''$first_name'';
-->
</script>

推荐答案

first_name'';

- >

< / script>

first_name'';
-->
</script>

您的意思是预先选择：

< input type = "无线电"检查>和

<选择选择值=" val">文字< /选项>

Do you mean preselected:
<input type="radio" checked> and
<option selected value="val">text</option>

大家好，


你没有用Javascript指定初始值。您可以用HTML指定它们：


< input type =" text" ... value =" initial value"


< input type =" checkbox" ...已检查>


< input type =" radio" ...已检查>


< select ...>

< option ... selected> ...< / option>

< / select>


< textarea ...>初始值< / textarea>


我建议你阅读HTML规范

（< URL：http：//www.w3.org/TR/html4/>），而不是依赖网络。

有关表格的信息，请参阅第17节

（< URL：http：//www.w3.org/TR/html4/interact/forms.html>）。


如果您有任何其他问题，请在alt.html或

comp.infosystems中询问。 www.authoring.html 。

语言属性已被弃用超过六年。请改为使用

类型属性：


< script type =" text / javascript">

使用SGML注释分隔符隐藏脚本是一种过时的做法。它不是必需的
。

//设置值：
document.PersProf.first_name.value =''

Hi All,

Been learning Javascript (via google) to create forms
with pre-set values.
You don''t specify initial values with Javascript. You specify them in HTML:

<input type="text" ... value="initial value">

<input type="checkbox" ... checked>

<input type="radio" ... checked>

<select ...>
<option ... selected>...</option>
</select>

<textarea ...>initial value</textarea>

I suggest you read the HTML Specification
(<URL:http://www.w3.org/TR/html4/>), rather than rely on the Web.
Information regarding forms can be found under section 17
(<URL:http://www.w3.org/TR/html4/interact/forms.html>).

If you have any further problems, please ask in alt.html or
comp.infosystems.www.authoring.html.

<script language="JavaScript">
The language attribute has been deprecated for over six years. Use the
type attribute instead:

<script type="text/javascript">
<!--
Hiding scripts with SGML comment delimiters is an obsolete practice. It''s
not necessary.
//setting the value:
document.PersProf.first_name.value = ''
