input 框长度限制和只能输入数字保留2位小数

 

                        style="width:317px"

                        οninput="if(value.length>50)value=value.slice(0,50)"

                        v-model="addData.tenantry"

                        :placeholder="$t('common.input')">

如果是50长度限制50

              

                        v-model="addData.rent_total"

                        type="number"

                        step="0.01"

                        min="0"

                        οninput="if(value.length>11)value=value.slice(0,11)"

                        οnkeyup="this.value= this.value.match(/\d+(\.\d{0,2})?/) ? this.value.match(/\d+(\.\d{0,2})?/)[0] : ''"

                        style="width:217px"

                        :placeholder="$t('common.input')">

 长度跟只能输入数字保留2位小数正则

如果使用输入法输入英文之后获取不到input框里面的值, 就把onkeyup键盘事件改为change 值改变事件就可以了
