提现金额须要知足条件js判断

// 解决首位直接输入 '0开头的数字'问题

this.inputModel = this.inputModel.toString() + curVal.toString()

this.inputModel = this.inputModel.replace(/[^\d.]/g,""); //清除“数字”和“.”之外的字符

this.inputModel = this.inputModel.replace(/\.{2,}/g,"."); //只保留第一个. 清除多余的

this.inputModel = this.inputModel.replace(".","$#$").replace(/\./g,"").replace("$#$",".");

this.inputModel = this.inputModel.replace(/^(\-)*(\d+)\.(\d\d).*$/,'$1$2.$3') //保留2位小数

if(this.inputModel.indexOf(".")< 0 && this.inputModel !=""){//以上已通过滤，此处控制的是若是没有小数点，首位不能为相似于 0一、02的金额

this.inputModel= parseFloat(this.inputModel);

}

//判断不能输入最大值

if(this.maxValue > 0 && this.maxValue < this.inputModel) {

this.inputModel = this.maxValue

}

const inputVal = this.inputModel

const len = inputVal.length

if(len == 1 && inputVal.charAt(0) == '.') {

this.inputModel = ''
