方法的原理是将多行文本写在一个函数体的多行注释内,然后,通过字符串解析函数,将多行文本分离出来,这样,整个文件内容也可以原封不动的复制到JS代码中。不过这个方法只在IE里支持,Firefox会将注释代码从函数体中移除。 Function.prototype.getMultiline=function() { varlines=newString(thi
You can use escaped newlines (\) at the end of each line of string to make a multi-line concatenation, for example: const str = ' \ Hello World! \ '; Things To Consider: The output will contain the whitespace/tabs etc. as they appear in your string. Whitespace after the slash c...
.replace(/{id}/g, '_' + counter);
But JS already has multiline strings with \?const str = 'foo\ bar';This is not a multiline string. It's line-continuation. It doesn't preserve newlines, which is the main reason for wanting multiline strings.You would need to do the following:...
MultiLineString 是零个或更多 geometry 或 geographyLineString 实例的集合。 MultiLineString 实例 下图显示了 MultiLineString 实例的示例。 如图中所示: 图1 显示的是一个简单的 MultiLineString 实例,其边界是其两个 LineString 元素的四个端点。 图2 显示的是一个简单的 MultiLineString 实例,因为只有 LineSt...
