我正在使用Blazor HTML,我有一个<section class="showContent">
,其中包含一个表单,我只想向单击“是”选项的用户显示,我希望默认情况下隐藏该表单。这是我的代码:
<h5 class="stath5"><span class="badge badge-secondary">5.</span> Business / Custom Work / Services</h5>
<p class="forPurpose">For tax purposes</p>
<p class="statp">Do you (or a non-member on your land) have business sales, custom work, or services of $10,000 a year or more yearly turnover?</p>
<label class="label-yes">
<input type="radio" class="option-input radio" name="example"/>
Yes
</label>
<label>
<input type="radio" class="option-input radio" name="example" />
No
</label>
@*If yes, display the following; if no, do not @* *@
<section class="showContent">
<p class="statp">Please specify the amount for which you have <span class="badge badge-danger">not</span> yet paid tax:</p>
<EditForm Model="@businessData" style="max-width:800px;" onkeydown="javascript: DisableEnterKey();">
<FluentValidator />
<div class="individualForms">
<label class="statlabel" for="businessReselling"> Business / Reselling:</label><br />
<InputNumber id="businessReselling" class="input" @bind-Value="@businessData.BusinessResellingGross" onwheel="this.blur()" placeholder="$BZ" autofocus />
<ValidationMessage For="() => businessData.BusinessResellingGross" />
</div>
<br /><hr class="statHR" />
<div class="individualForms">
<label class="statlabel" for="pavementTax"> Pavement tax:</label><br />
<InputNumber id="pavementTax" class="input" @bind-Value="@businessData.PavementTaxGross" onwheel="this.blur()" placeholder="$BZ" />
<ValidationMessage For="() => businessData.PavementTaxGross" />
</div>
<br /><hr class="statHR" />
<div class="individualForms">
<label class="statlabel" for="customWrkServices"> Custom Work / Services:</label><br />
<InputNumber id="customWrkServices" for="customWrkServices" class="input" @bind-Value="@businessData.CustomWorkServicesGross" onwheel="this.blur()" placeholder="$BZ" />
<ValidationMessage For="() => businessData.CustomWorkServicesGross" />
</div>
</EditForm>
</section>
这似乎很简单,但我尝试了一些在线列出的方法,但这些方法对我而言并不起作用。

最简单的方法是引入一个布尔变量并将<section>
包裹在其中:
剃须刀页面:
<label class="label-yes">
<input type="radio" class="option-input radio" name="example" @onchange="OnUpdated"/>
Yes
</label>
@if (ShowSection)
{
<section class="showContent">
...
</section>
}
代码:
要显示该部分时请更改ShowSection = true
,而要隐藏它时请更改false
:
public bool ShowSection { get; set; }
public void OnUpdated(ChangeEventArgs e)
{
ShowSection = ((bool)e.Value);
}
