我有一个页面,其中有一个带有选项下拉列表的表单,然后是一个对话框,您可以在其中更改所选选项的详细信息。从下拉列表(select
标记)中选择了一个选项后,我无法更新对话框表单(无默认值)。
代码可能看起来有点奇怪,它是由parenscript和cl-who(Common Lisp库)自动生成的。
代码如下:
function openFuns(form) {
var frm = getElementById('editPass');
return frm.date.value = form.passList.options[form.passList.selectedIndex].value;
};
function init() {
_js72 = document.getElementById('editPassDialog');
document.getElementById('getPass').onclick = function () {
return _js72.showModal();
};
return document.getElementById('submitPass').onclick = function () {
return _js72.close();
};
};
window.onload = init;

所以理想的行为是,它会更新对话框中的日期字段,其中包含所选选项的任何内容,从下拉列表&#34; Passes&#34;,但这没有发生。我知道表单数据已正确传递给函数openFuns()
,因为如果我使用console.log
或alert
,它会显示所选选项的信息。

所以,这是jsfiddle:

</p>
<p>Email
<input type='email' name='email' class='txt' value='test2@gmail.com' />
</p>
<p>Passes
<select name='passList'>
<option id='pass' value='(TYPE M DATE 2015-01-05T20:33:05.000000+09:00 AMT
17000)'>Jan 2015
</option>
<option id='pass' value='(TYPE W DATE 2014-12-29T20:00:38.000000+09:00 AMT 6000)'>Dec 2014
</option>
</select>
<button type='button' id='getPass' class='btn'>Get Pass

</p>

<input type='submit' value='Edit Info' class='btn' />
</p>
</form>
<dialog id='editPassDialog'>

<form action='edit-pass' method='post' id='editPass'>
<p>Date bought

<p>Type
<input type='text' name='type' class='txt'></input>
</p>
<p>Amount Paid

JS:
_js72 = document.getElementById('editPassDialog');
document.getElementById('getPass').onclick = function () {
var frm = document.getElementById('editPass');
var form = document.forms.namedItem("editStudent");
frm.date.value = form.passList.options[form.passList.selectedIndex].value;
return _js72.showModal();
};
document.getElementById('submitPass').onclick = function () {
return _js72.close();
};
日期传递到该字段。 (传递选项的值)要传递选项的html使用innerHtml属性,就像我在这里做的那样:

另外,我建议你至少使用jquery / bootstrap。例如,对话框元素仅在chrome和opera中受支持:http://caniuse.com/#search=dialog
