Javascript正则表达式模式没有钱没有货币的价值

Question

我正在寻找一个允许插入或注册这些金额

的javascript正则表达式模式

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class WebViewActivity extends Activity {

    private WebView webView;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        webView = (WebView) findViewById(R.id.webView1);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("http://www.google.com");

    }

}

但这些数字不应小于0.我设法找到模式，但我想省略“$”。我想要的只是数字，逗号和点数

5
5.1
5.10
5
500,000
500,000.1
500,000.10

Answer 1

删除\$?

/^\d+(,\d{3})*(\.\d*)?$/

＆＃13;

＆＃13;

var x = 5000;
var a = "5,000,000"
var y = "$5,,,000,000"
var z = "500,000"
var c = "c231"
var d = "1...0.00"
var e = "..."
var f = "1.00,,,"

var validRegEx = /^\d+(,\d{3})*(\.\d*)?$/;

console.log(x," Valid", validRegEx.test(x))
console.log(a," Valid", validRegEx.test(a))
console.log(y," Valid", validRegEx.test(y))
console.log(z," Valid", validRegEx.test(z))
console.log(c," Valid", validRegEx.test(c))
console.log(d," Valid", validRegEx.test(c))
console.log(e," Valid", validRegEx.test(c))
console.log(f," Valid", validRegEx.test(c))

Answer 2

根据我对问题的评论，新代码将是

var x = 5000;
var a = "5,000,000"
var y = "$5,,,000,000"
var z = "500,000"
var c = "c231"
console.log(x," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(x))
console.log(a," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(a))
console.log(y," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(y))
console.log(z," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(z))
console.log(c," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(c))

尝试

^\$?([0-9]{1,3},([0-9]{3},)*[0-9]{3}|[0-9]+)(\.[0-9][0-9])?$
