问题描述
我在JavaScript中使用regexp尝试测试字符串。
正确的字符串看起来像：
I try test string using regexp in JavaScript.Correct string looking like:
<script charset="utf-8">new DGWidgetLoader({"width":640,"height":600,"borderColor":"#a3a3a3","pos":{"lat":46.00650100065259,"lon":11.263732910156252,"zoom":9}
我想测试width，height看起来像xxx或xxxx，以及lat，lon
看起来像x {1,2} .x *，缩放看起来像x {1,2}
I want test that "width", "height" looks like xxx or xxxx, and "lat", "lon" looks like x{1,2}.x*, zoom looks like x{1,2}
我尝试使用这个正则表达式
I try use this regex
/<script charset="utf-8">new DGWidgetLoader(/{"width":[0-9]{3,4},"height":[0-9]{3,4},"borderColor":"#a3a3a3","pos":\{"lat":[0-9]{1,2}.[0-9]+,"lon":[0-9]{1,2}.[0-9]+,"zoom":[0-9][0-9]}//
使用String.search（），但收到错误 SyntaxError：无效的正则表达式：/< script charset =utf -8> new DGWidgetLoader（/ {width：[0-9] {3,4}，height：[0-9] {3,4}，borderColor：＃a3a3a3， POS ：{ LAT ：[0-9] {1,2} [0-9] +， LON ：[0-9] {1,2} [0-9] +， 变焦：[0-9] [0-9]} //：未终止的群组
with String.search(), but got error SyntaxError: Invalid regular expression: /<script charset="utf-8">new DGWidgetLoader(/{"width":[0-9]{3,4},"height":[0-9]{3,4},"borderColor":"#a3a3a3","pos":{"lat":[0-9]{1,2}.[0-9]+,"lon":[0-9]{1,2}.[0-9]+,"zoom":[0-9][0-9]}//: Unterminated group
我如何解析如下所示的脚本标记？
How can i parse script tag that looking like below?
推荐答案
你应该逃避（， {，} 和。使用 \ ：
You should escape (, {, } and . with \:
/<script charset="utf-8">new DGWidgetLoader\(\{"width":[0-9]{3,4},"height":[0-9]{3,4},"borderColor":"#a3a3a3","pos":\{"lat":[0-9]{1,2}\.[0-9]+,"lon":[0-9]{1,2}\.[0-9]+,"zoom":[0-9][0-9]\}/
