I am looking to eliminate all non-numeric symbols and punctuations except for periods ".". I have managed to remove all non-numeric symbols using the following code:
if (!/^[0-9]+$/.test(this.value)) {
this.value = this.value.replace(/\D/, "");
}
Can someone guide me on how to achieve this? Thank you for your assistance.
The pattern \D will find any character that is not a digit.
To exclude a dot as well, you can utilize a negative character class like [^\d.]+, which matches any character except a dot or digit.
In this case, since you are replacing it with an empty string, the character class can be repeated 1+ times.
Don't forget to use the global flag /g to replace all instances.
this.value = this.value.replace(/[^\d.]+/g, "");
var newValue = this.value.replace(/[^\d\.]/g, "");
