替换所有相同的字符串Javascript

Question

I want to Replace 2013-2-2 to 2013,2,2 我想将2013-2-2替换为2013,2,2

I tried 我试过了

var forrep = '2013-2-2'; 

var text = forrep.replace('-', ',');

but it only replaces the first - the output looks like this 2013,2-2 但它只会替换第一个-输出看起来像这样2013,2-2

I want all the - to be replaced by , commna 我希望所有的-要被替换, commna

将正则表达式与/g开关一起使用，以使其与“全局”匹配：

var text = forrep.replace(/-/g, ',');
