If a form has the structure below:
<form>
<input type="text" required ng-model='myValue' ng-maxlength='5'></input>
{{myValue}}
{{myValue.length}}
</form>
Is there a way to prevent the model from becoming empty when the text in the input exceeds the maxlength, without creating a custom form level validator?
Initially, the input element does not have an end mark (</input). The correct format is as follows:
<input name="test" type="text"/>You can use form.test.$error.maxlength to handle certain situations. Here is an example code snippet:
<form name="form">
<input name="name" type="text" required ng-model='myValue' ng-maxlength='5'/>
<div>value:{{myValue}}</div>
<div>length:{{myValue.length}}</div>
<div>validate:{{form.name.$error.maxlength}}</div>
</form>
According to your explanation, an invalid value results in a null model, which I believe is not a problem.
