javascript - splitPinCodes.split (',' )给出错误

Question

我在验证输入时遇到错误。我在输入文本区域中得到以逗号分隔的 6 位邮政编码。我在输入文本区域应用了 ng-change="convertToArray()"( Angular 方法)。

当我输入超过 6 位数字且不带逗号(,) 时，会出现错误

HTML 文件

$scope.convertToArray=function(){
		var splitPinCodes = $scope.cluster.pincode;
		$scope.toArray = splitPinCodes.split(',');
		
	}

<div class="page page-tasks ng-scope main-div ">
	<div class=" callout-elem-info ng-scope cntrl-div"
		data-ng-controller="mobilizationsettings">
		<form name="ClusterInfoForm" class="add-task table form-validate" novalidate>
			<div class="ng-scope left-div">

				<div layout layout-sm="column">
					<h3>Cluster No.1</h3>

					<md-input-container flex class="clusterName">
					<label>Cluster Name</label> <input id="inputCLusterName"
						ng-pattern="/^[a-zA-Z ]*$/" type="text" ng-model="cluster.Name"
						maxlength="40" placeholder="Enter Cluster Name"
						class="form-control required" required /> </md-input-container>
				</div>

				<div layout layout-sm="column">
					<md-input-container flex> <label>Cluster
						PinCodes</label> <input id="inputCLusterPincodes"
						ng-pattern="/^[1-9][0-9]{5}(?:,[1-9][0-9]{5})*$/" type="text"
						ng-model="cluster.pincode" ng-change="convertToArray()"
						placeholder="Enter Cluster PinCode" class="form-control " /> </md-input-container>

					<div class="addPinCode-div">
						<md-button required ng-model="newEntry" 
							class="btn-width-medium md-raised md-primary btn-lg md-button md-default-theme md-button addPinCodeButton"
							ng-click="addNewPinCode($data,$event)"> ADD
						PINCODE(S) </md-button>
					</div>
					&nbsp;
				</div>

所以请帮助我寻找其他替代方案。

如果未找到分隔符，则 split 将不执行任何操作。重写如下，它应该可以工作:

$scope.convertToArray=function(){
     if($scope.cluster.pincode.indexOf(',')==-1){
         $scope.toArray = [$scope.cluster.pincode];
     }else{
    var splitPinCodes = $scope.cluster.pincode;
        $scope.toArray = splitPinCodes.split(',');
     }
}

编辑:

when I entered more than 6 digit without comma(,) it gives error

是的，这就是你的 ng-pattern 所说的:“如果超过 6 个字符且没有逗号，则崩溃”。
