我想要在表单有效时保持启用提交表单的按钮:
<button class="button button-clear button-positive" ng-click="submitForm(data)" ng-disabled="myForm.$invalid">
Salvar
</button>
<form name="myForm">
<label class="item item-input">
<span class="input-label">Nome</span>
<input type="text" placeholder="Nome da categoria" ng-model="data.Categoria.name" required>
</label>
</form>
我认为问题是按钮在表单之前,所以他们没有“看到”myForm。$ invalid。如果你问我为什么我不能把按钮放在窗体里面,是因为这个按钮在应用程序的条形标题上,而且表格是下面的。
我该如何处理这种情况?

您可以使用ng-form指令。 ng-form
<button class="button button-clear button-positive" ng-click="submitForm(data)" ng-disabled="myForm.$invalid">
Salvar
</button>
<div data-ng-form name="myForm">
<label class="item item-input">
<span class="input-label">Nome</span>
<input type="text" placeholder="Nome da categoria" ng-model="data.Categoria.name" required>
</label>
</div>

您可以尝试设置包含两个控件的表单:
<form name="myForm">
<button class="button button-clear button-positive" ng-click="submitForm(data)" ng-disabled="myForm.$invalid">
Salvar
</button>
<label class="item item-input">
<span class="input-label">Nome</span>
<input type="text" placeholder="Nome da categoria" ng-model="data.Categoria.name" required>
</label>
</form>
或者如果您不想破坏布局或不需要表单,请ng-form directive:
<div class="item item-input-inset" ng-form="myForm">
<button class="button button-clear button-positive" ng-click="submitForm(data)" ng-disabled="myForm.$invalid">
Salvar
</button>
<label class="item item-input">
<span class="input-label">Nome</span>
<input type="text" placeholder="Nome da categoria" ng-model="data.Categoria.name" required>
</label>
</div>
