輸入為空時 ng-show 顯示錯誤

Question

好吧，我有 ：

<div class="form-group">
<label for="address" class="control-label col-lg-5 col-md-6">                                @Html.Label(@Translator.Translate("STREET_ADDRESS")):
<span ng-show="editUserForm.Address.$error.required" class="required">*</span>
</label>
<div class="col-lg-7 col-md-6">
@Html.TextBoxFor(m => m.Address, new {name="Address", @class = "form-control", id = "address", @maxlength = "30", ng_model = "address", @required = "required", ng_pattern = @"/[A-Za-z]+ ?[0-9]+$/" })
</div>
</div>

所以我的想法是當這個文本框為空時顯示 * 但對我來說它不起作用......有幫助嗎？

Answer 1

（移自評論）將跨度更改為：

<span ng-show="!address">*</span>

Answer 2

嘗試這個

   <span ng-show="editUserForm.Address.$dirty && editUserForm.Address.$error.required" class="required">*</span>
