问如何在RegExp插件中修复这样的jQuery错误？

EN

/(?![^&;]+;)(?!<[^<>])(C\+\+)(?![^<>]>)(?![^&;]+;)/

function escapeRegex(str) {
  return str.replace(/[-\/\\$\^*+?.()|\[\]{}]/g, '\\$&');
}

var re = new RegExp(escapeRegex('[.*?]'));

function find_value_and_highlight_term(template, value, term) {
  var templateLc = template.toLowerCase();
  var strpos = templateLc.indexOf(term);
  if(strpos) {
    var strlen = term.length;
    var templateStart = template.slice(0,strpos);
    var templateEnd = template.slice(strpos+strlen);
    return templateStart+"<b>"+term+"</b>"+templateEnd;
  } else {
    return template;
  }
}

Here I have found solution of "c++" string during searching in tokeninput js.
you just search code in jquery.tokeninput.js and replace with code below.

here are the function:

 function regexSanitize( str ) {
   return str.replace(/([.+*?:\[\](){}|\\])/g, "\\$1");
  }

  function highlight_term(value, term) {
    return value.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + regexSanitize(value) + ")(?![^<>]*>)(?![^&;]+;)", "gi"), "<b>$1</b>");
    }



 function find_value_and_highlight_term(template, value, term) {
       return template.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + regexSanitize(value) + ")(?![^<>]*>)(?![^&;]+;)", "g"), highlight_term(value, term)
);
