系统有个栏位,作为参数设置,限制用户只能输入大于0的正整数:

<input type="text" name="non" ng-model="non" onpaste="return false;" onkeyup="if ( this.value.length == 1 ) { this.value = this.value.replace(/[^1-9]/g, '') } else { this.value = this.value.replace(/D/g, '') }" onafterpaste="if ( this.value.length == 1) { this.value = this.value.replace(/[^1-9]/g, '0') } else { this.value = this.value.replace(/D/g, '') }" />
上面有一个onpaste属性,即是说,此文本框不接受粘贴数据。
