[英]Extract lat/lng coordinates from a string
I've got a string which contains several coordinates.我有一个包含多个坐标的字符串。 It is just random human readable text.
它只是随机的人类可读文本。 For example:
例如:
Bla bla bla 35.45672,-162.91938 yadda yadda yadda -6.53197, 132.07407 bla bla
I would like to extract all the coordinates from the text to an array.我想将文本中的所有坐标提取到一个数组中。 The coordinates are seperated by a comma, or a comma and a space (As in the example above).
坐标由逗号或逗号和空格分隔(如上例所示)。 There is no fixed length or seperators.
没有固定的长度或分隔符。 There is no fixed amount of coordinates.
没有固定数量的坐标。 It is just random text containing lat/lng coordinates.
它只是包含纬度/经度坐标的随机文本。
What would be the best way to extract all coordinates from the text into an array?将文本中的所有坐标提取到数组中的最佳方法是什么?
You could use match()
here with an appropriate regex pattern:您可以在此处使用带有适当正则表达式模式的
match()
:
var input = "Bla bla bla 35.45672,-162.91938 yadda yadda yadda -6.53197, 132.07407 bla bla"; var matches = input.match(/-?\d+(?:\.\d+)?,\s*-?\d+(?:\.\d+)?/g); console.log(matches);
Once you have isolated the lat/lng pairs in the above string array, it is only a bit more work to obtain separate numbers in whatever format you need.在上述字符串数组中分离出 lat/lng 对后,只需多做一点工作即可获得所需格式的单独数字。
