weex input number limit
use component, when i input content,it has a limit condation,only input number length is 8,and only 2 radix point,for example,can input 123.45, 123.456 is not.
<input :type="type"
v-model="inputValue"
:max-length="maxInputLength"
:maxlength="maxInputLength"
:placeholder="rightPlaceholder"
:class="['input', disabled ? 'input-style-disabled' : '']"
:disabled="disabled"
@input="onTextChange"/>
and data is :
data () {
return {
inputValue:'', //input value
}
},
mounted(){
if(this.value) {
this.inputValue = this.value;
}
},
methods:{
formatAmount(value){
let result;
if (value.indexOf(".") > 0 && value.length - value.indexOf(".") >= 4){
result = value.substr(0,value.indexOf('.') + 3);
// fValue = value.toFixed(2);
Log.d("formatAmount",result);
}else {
result = value;
Log.d("formatAmount else",result);
}
return result;
},
onTextChange() {
setTimeout(() => {
this.inputValue = this.formatAmount(this.inputValue);
this.$emit("onTextChange",this.inputValue);
}, 10);
}
}
totally,this just work when two point change to three point,then still can input three point.
how does it work,need help.thx.

You can use array split on (.) and then check arr[1].length<=2 and arr[0].length <=6.or use regex /^d+(.d{1,2})?$/ for 2 radix point;
