如果选中复选框,则应启用文本框,否则应禁用文本框。
不知道为什么这段代码不起作用?
<script type="text/javascript">
function toggleTB(what){
if(what.checked){document.test.from_address.disabled=1}
else{document.test.from_address.disabled=0}}
</script>
<% form_for(@test,:name => "test") do |f| %>
<table>
<tr>
<td class="right upcase none">
<%= f.label 'text_enabled', "Enable",:class => "capitalize none" %>
<%= f.check_box :text_enabled,:onclick => "toggleTB(this)" %>
</td>
</tr>
<tr>
<td class="right upcase none">
<%= f.label 'from_address', "From Address",:class => "capitalize none" %>
</td>
<td>
<%= f.text_field 'from_address', :maxlength => 16 %>
</td>
</tr>
</table>
<% end %>
任何想法?

Try like this
<script type="text/javascript">
function toggleTB(what){
if(what.checked){document.getElementById('from_address').disabled=1}
else{document.getElementById('from_address').disabled=0}}
</script>
<input type="checkbox" name="toggle" onclick="toggleTB(this)"/>
<input type="input" id="from_address" />

尝试设置disabled = true
和disabled=false
.. text_box的ID也是test_from_address
,名称将是test[from_address]
。

尝试在第3行的末尾设置disabled=disabled

这对我有用..
<script type="text/javascript">
<!--
function toggleTB(what){
document.getElementById("test_from_address").disabled = !what.checked;
}
-->
</script>
<% form_for(@test,:name => "test") do |f| %>
<table>
<tr>
<td class="right upcase none">
<%= f.label 'text_enabled', "Enable",:class => "capitalize none" %>
<%= f.check_box :text_enabled,:onclick => "toggleTB(this)" %>
</td>
</tr>
<tr>
<td class="right upcase none">
<%= f.label 'from_address', "From Address",:class => "capitalize none" %>
</td>
<td>
<%= f.text_field 'from_address', :maxlength => 16 %>
</td>
</tr>
</table>
<% end %>
