如果我有这样的一条线:
文本:1.10.0.1001
i m looking 欲获得版本编号,但可以说明如何获得以下插图:
从未见过
(?<=转化:......)。 * E/CN.6/2009/1。
这张旗号包括“颠覆”:“相匹配,之后将具有任何特性。
Use parantheses to capture values. If you only want the entire version value in one string, this would be enough
if(/version is:(.*)/.test(yourString)) {
versionNum = RegExp.$1;
}
页: 1 Num将储存1.10.0.1001。
但是,如果你想要在十字路口之间找到具体数字,那么你就不得不这样做:
if(/version is:(d+.)(d+.)(d+.)(d+)/.test(yourString)) {
majorBuild = RegExp.$1;
minorBuild = RegExp.$2;
patch = RegExp.$3;
revision = RegExp.$4;
}
基本上,变量将具有类似数值的数值。
majorBuild = 1
minorBuild = 10
patch = 0
revision = 1001
Cheers!
使用一种捕获(表面)。 提 出
s/version is:(.*)/1/g
另外,你利用了何种雷管发动机? 你们也许需要逃离殖民地,确定魔 on是否在/起飞
或更糟的是,删除案文:它面前的一切事项。
s/.*version is://g
