这是html代码,我想制作一个指令
<div class="form-group" ng-class="{'has-success':signupForm.username.$touched && signupForm.username.$valid,'has-error':signupForm.username.$touched && signupForm.username.$invalid,'has-feedback':signupForm.username.$touched }">
<input tabindex="1" type="text" class="form-control" placeholder="username" ng-model="authCtrl.user.username" required ng-minlength='5' ng-maxlength='10' name="username" ng-pattern="/^[a-z0-9]*$/">
<span class="glyphicon" ng-show="signupForm.username.$touched" ng-class="{'glyphicon-ok form-control-feedback':signupForm.username.$touched && signupForm.username.$valid,'glyphicon-remove':signupForm.username.$touched && signupForm.username.$invalid,'form-control-feedback':signupForm.username.$touched}"></span>
<div ng-messages="signupForm.username.$error" ng-show="signupForm.username.$touched">
<div ng-messages-include="/static/app/components/widget/widget.view.input-error.html"></div>
</div>
</div>
但我无法弄清楚,如何为任何组件传递变量,即formname.inputname。$ error
更新:目前为止进展:
模板:
<widget-form-input
input-type='authCtrl.input.username.type'
input-placeholder='authCtrl.input.username.placeholder'
input-name='authCtrl.input.username.name'
input-model='authCtrl.user.username'></widget-form-input>
指令:
function widgetFormInput(){
var input = {};
input.restrict = 'E';
input.scope = {
'inputType' : '=',
'inputPlaceholder' : '=',
'inputName' : '=',
'inputModel' : '=',
'inputMaxlength' : '=?',
'inputMinlength' : '=?',
'inputPattern' : '=?',
}
input.templateUrl = '/static/app/components/widget/widget.view.form-input.html';
return input;
}
指令模板:
<div class="form-group" ng-class="{'has-success':signupForm.inputName.$touched && signupForm.inputName.$valid,'has-error':signupForm.inputName.$touched && signupForm.inputName.$invalid,'has-feedback':signupForm.inputName.$touched }">
<input tabindex="1" type="text" class="form-control" placeholder="{{inputPlaceholder}}" ng-model="inputModel" required ng-minlength='inputMinlength' ng-maxlength='inputMaxlength' name="{{inputName}}" ng-pattern="inputPattern">
<span class="glyphicon" ng-show="signupForm.inputName.$touched" ng-class="{'glyphicon-ok form-control-feedback':signupForm.inputName.$touched && signupForm.inputName.$valid,'glyphicon-remove':signupForm.inputName.$touched && signupForm.inputName.$invalid,'form-control-feedback':signupForm.inputName.$touched}"></span>
<div ng-messages="signupForm.inputName.$error" ng-show="signupForm.inputName.$touched">
<div ng-messages-include="/static/app/components/widget/widget.view.input-error.html"></div>
</div>
答案 0 :(得分:0)
您已将inputname作为inputName传递。这可以。您还需要传递表单名称。但是你正在创建隔离范围。也传递表单名称,如下所示:
<widget-form-input
input-type='authCtrl.input.username.type'
input-placeholder='authCtrl.input.username.placeholder'
input-name='authCtrl.input.username.name'
input-model='authCtrl.user.username'
form-name='signupForm'></widget-form-input>
更新指令范围,如下所示:
input.scope = {
'inputType' : '=',
'inputPlaceholder' : '=',
'inputName' : '=',
'inputModel' : '=',
'inputMaxlength' : '=?',
'inputMinlength' : '=?',
'inputPattern' : '=?',
'formName' : '@' //This will be treated as a string
}
最后,更新您的指令模板,如下所示:
<div class="form-group" ng-class="{'has-success':formName.inputName.$touched && formName.inputName.$valid,'has-error':formName.inputName.$touched && formName.inputName.$invalid,'has-feedback':formName.inputName.$touched }">
您需要在指令模板中的任何位置更新硬编码的表单名称,以指向formName变量。
