Regex 替换保留为JSON中键值的字符串中的模式匹配项

我有一个JSON文件，它有一个键值对，如下所示

{
    "parameters": "<FieldLabel Type='Something'><Label><![CDATA[Click on this number to initiate call <a href='tel:123456' parameter='DialMe,100.200.3000'>100.200.3000'>100.200.3000'>100.200.3000'>tel:1002003000'>100.200.3000</a> or<a href='tel:911'parameter='dial911,911'>911'>911'>911'>tel:911'>911</a>  ]]></Label><Description><![CDATA[]]></Description></FieldLabel>"
 }

及

在使用Angular的ng bind HTML和$sce.trustAsHtml将其呈现为HTML之前。 关键是JSON有许多这样的键值对，每个键值对的参数值都不同，比如parameter=dial108108。因此不可能进行正常的字符串替换。我应该如何为每个键值对进行替换？

尝试以下方法：

var str = "<FieldLabel Type='Something'><Label><![CDATA[Click on this number to initiate call <a href='tel:123456' parameter='DialMe,100.200.3000'>100.200.3000'>100.200.3000'>100.200.3000'>tel:1002003000'>100.200.3000</a> or<a href='tel:911'parameter='dial911,911'>911'>911'>911'>tel:911'>911</a>  ]]></Label><Description><![CDATA[]]></Description></FieldLabel>";

str = str.replace(/parameter=\'.*,/g, function(s){
    return s.replace("parameter", "my-url-click") + "null,null,"
});

parameter='dial911,911' with my-url-click='dial911,null,null,911' 

var str = "<FieldLabel Type='Something'><Label><![CDATA[Click on this number to initiate call <a href='tel:123456' parameter='DialMe,100.200.3000'>100.200.3000'>100.200.3000'>100.200.3000'>tel:1002003000'>100.200.3000</a> or<a href='tel:911'parameter='dial911,911'>911'>911'>911'>tel:911'>911</a>  ]]></Label><Description><![CDATA[]]></Description></FieldLabel>";

str = str.replace(/parameter=\'.*,/g, function(s){
    return s.replace("parameter", "my-url-click") + "null,null,"
});
