Javascript将“'”替换为“''”
我试图用替换方法替换“'”字符与“''”字符串，如下所示：
temp.replace("'", "''");
但它似乎并没有取代任何东西。 我应该如何编写命令以便用想要的字符串替换想要的字符（我试图在下一个xml中替换它）：
<Module ForceTabs="1">

<Event Value="onafter_moduleinit_beforedraw()" Type="onafter_moduleinit_beforedraw"/>

我必须将单曲替换为两首单曲，我不能将其改为“但是”
while (str.indexOf("'") >= 0)
{
var newStr = str.replace("'", """);
str = newStr;
}
你的代码只是替换一个实例（它找到的第一个实例）。 您应该替换所有实例。 您可以通过使用正则表达式并在末尾添加一个g标志来表示“全局搜索”。 喜欢这个：
temp.replace(/'/g, "''")
这是一个工作示例：http://jsfiddle.net/Q2Uyv/（在“In”框中键入内容并单击“Convert”）。
如果您实际上试图用双引号替换单引号（而不是双引号单引号），请执行以下操作：
temp.replace(/'/g, '"')
问题在于
temp.replace("'", "''");
将只会取代'的第一个实例。 要解决这个问题，请改为执行以下操作
temp.replace(/'/g, "''"));
这样可以确保它能够代替单引号的所有实例，而不仅仅是第一个。
