嗨，我是Angle JS的新手吗？用户输入十进制值或显示角度js错误的字符串时，如何仅在texbox中允许数字？
<div class="col-md-6 col-sm-6">
<label class="col-md-5 col-sm-5 pad-top5 pad-lft-no">Min <span class="error">*</span></label>
<input positive type="number" class="col-md-7 col-sm-7 cls_input_inherit numberinput" min="0" ng-maxlength="3" id="age_min" name="age_min" ng-model="attributes.age_min" required/>
<label for="age_min" ng-show="submittab2 && attributesForm2.age_min.$error.required" class="error">{{formValidation.required}}</label>
<label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && attributesForm2.age_min.$error.maxlength" class="error"> {{formValidation.monthMaxChar}} </label>
<label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && !attributesForm2.age_min.$error.maxlength && attributesForm2.age_min.$error.min" class="error">{{formValidation.minMax}}</label>
<label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && !attributesForm2.age_min.$error.maxlength && attributesForm2.age_min.$error.number" class="error">{{formValidation.errorNumber}}</label>
<label for="age_min" ng-show="submittab2 && attributesForm2.age_min.$error.positive" class="error">{{formValidation.minpositive}}</label>
</div>
是否尝试上述代码，但输入十进制值时未显示错误？如何解决？
您需要在输入字段中添加ng-pattern =“ / ^（\ d）+ $ /”。
<div class="col-md-6 col-sm-6">
<label class="col-md-5 col-sm-5 pad-top5 pad-lft-no">Min <span class="error">*</span></label>
<input positive type="number" class="col-md-7 col-sm-7 cls_input_inherit numberinput" min="0" ng-maxlength="3" id="age_min" name="age_min" ng-model="attributes.age_min" ng-pattern="/^(\d)+$/" required/>
<label for="age_min" ng-show="submittab2 && attributesForm2.age_min.$error.required && attributesForm2.age_min.$touched && attributesForm2.age_min.$invalid" class="error">{{formValidation.required}}</label>
<label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && attributesForm2.age_min.$error.maxlength" class="error"> {{formValidation.monthMaxChar}} </label>
<label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && !attributesForm2.age_min.$error.maxlength && attributesForm2.age_min.$error.min" class="error">{{formValidation.minMax}}</label>
<label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && !attributesForm2.age_min.$error.maxlength && attributesForm2.age_min.$error.number" class="error">{{formValidation.errorNumber}}</label>
<label for="age_min" ng-show="submittab2 && attributesForm2.age_min.$error.positive" class="error">{{formValidation.minpositive}}</label>
</div>
