javascript - 正则表达式附加字符并删除结束双引号

Question

我已经尝试在正则表达式下面从中捕获一些字符串:

    "CallbackFnCreate_[\W]{4}(.*?[^\w-])

Required Output should be : /TestResult_20190604-120620 (Capture 
TestResult_20190604-120620 and append "/" in the beginning)

我的第 1 组输出是:TestResult_20190604-120620"

1|#||4|3952|updatePanel|WorkflowFileExplorer_ajaxPanel|<div `id="WorkflowFileExplorer_pbContainer" style="width:0px;height:0px;overflow:hidden;position:relative;"><input type="button" name="WorkflowFileExplorer$pb" value="pb" onclick="javascript:__doPostBack(&#39;WorkflowFileExplorer$pb&#39;,&#39;&#39;)" id="WorkflowFileExplorer_pb" tabindex="-1" /><input name="WorkflowFileExplorer$postbackArgument" type="hidden" id="WorkflowFileExplorer_postbackArgument" value="CallbackFnCreate_/***TestResult_20190604-120620" /></div><div id="WorkflowFileExplorer_tree" class="RadTreeView RadTreeView_Default">`

Answer 1

我的猜测是我们希望简单地进行替换并稍微修改原始表达式:

.+("CallbackFnCreate_\/\*\*\*(.+?)").+

我们想要的输出在这个捕获组中:

(.+?)

测试

const regex = /.+("CallbackFnCreate_\/\*\*\*(.+?)").+/gm;
const str = `1|#||4|3952|updatePanel|WorkflowFileExplorer_ajaxPanel|<div \`id="WorkflowFileExplorer_pbContainer" style="width:0px;height:0px;overflow:hidden;position:relative;"><input type="button" name="WorkflowFileExplorer\$pb" value="pb" onclick="javascript:__doPostBack(&#39;WorkflowFileExplorer\$pb&#39;,&#39;&#39;)" id="WorkflowFileExplorer_pb" tabindex="-1" /><input name="WorkflowFileExplorer\$postbackArgument" type="hidden" id="WorkflowFileExplorer_postbackArgument" value="CallbackFnCreate_/***TestResult_20190604-120620" /></div><div id="WorkflowFileExplorer_tree" class="RadTreeView RadTreeView_Default">\`
`;
const subst = `\/$2`;

// The substituted value will be contained in the result variable
const result = str.replace(regex, subst);

console.log('Substitution result: ', result);
