我正在尝试使用 knockout.js 的可见绑定在选择的值之间进行切换，并取决于选择的值。当值为 = '5' 我想切换元素时，谁能解释我哪里出错了？我也在 foreach 中执行此操作，也许我的变量范围不适合比较？谢谢
<table border="1" cellpadding="4" cellspacing="0" id="terms_table">
<thead>
<tr class="term_row">
<th><div align="center">Percentage</div></th>
<th><div align="center">Payment Terms</div></th>
<th><div align="center">Stage</div></th>
<th><div align="center">Delete</div></th>
</tr>
</thead>
<tbody data-bind="foreach: terms" >
<tr class='spec_row'>
<td class='center'><input size='5' data-bind="value : percentage" /></td>
<td class='center'>
<select data-bind='visible: $data.term != 5, options: $parent.termOptions,
value: $data.term, optionsValue: "id", optionsText: "option"'></select>
<input data-bind='value: other, visible: $data.term == 5 ' />
</td>
<td class='center'><input size='60' data-bind="value : stage" /></td>
<td class='center' valign='middle'>
<input type='hidden' data-bind="value : id" />
<input type='hidden' data-bind="value : rank" />
