我正在使用类型编号的输入,它允许多个小数点,所以我尝试使用正则表达式不允许超过一个小数点,但即使使用正则表达式我面临相同的问题,任何人都可以告诉我如何在ionic1
中输入类型编号只允许一个小数点HTML:
<input stopccp focus-me class="inputContainer trade_input" type="number" name="" ng-model="vm.total_amount[$index]" ng-change="vm.onTotalCost()" limit-char limit="5" ng-keyup="vm.decimalcheck(vm.total_amount[$index])" >
功能正则表达式:
function decimalcheck (element) {
$log.log('decimalcheck got called', element);
var regex = /\d*\.?\d?/g;
return regex.exec(element);
}

我想你只是错过了开始(^)和结束($)运算符
function decimalcheck (element) {
$log.log('decimalcheck got called', element);
var regex = /^\d*\.?\d?$/g;
return regex.exec(element);
}

试试这个正则表达式:
^\d*\.?\d+$
<强>解释强>
^
- 字符串开头\d*
- 0+位数\.?
- 0或1小数点\d+
- 1+位数(因此必须在小数点后至少有一位数,如果存在的话)$
- 字符串结尾
