Question

我正在尝试替换字符串中值的所有出现以及另一个值

到目前为止我所拥有的是

var result = "Cooker Works" 
var searchterm = "cooker wor";

searchterm.split(" ").forEach(function (item) {
   result = result.replace(new RegExp(item, 'g'), "<strong>" + item + "</strong>");
});
    
console.log(result)

我所追求的结果应该是

result = "<strong>Cooker</strong> <strong>Wor</strong>s";

我在处理案件时遇到问题，我有什么方法可以忽略这一点并仍然得到我追求的结果

Answer 1

您需要对不区分大小写的匹配使用i修饰符

new RegExp(item, 'ig')

var result = "Cooker Works"
var searchterm = "cooker wor";

searchterm.split(" ").forEach(function(item) {
  var matchs = result.match(new RegExp(item, 'ig'));
  if (matchs.length)
    result = result.replace(new RegExp(item, 'ig'), "<strong>" + matchs[0] + "</strong>");
});

console.log(result)

Answer 2

您将使用捕获组和i（ignoreCase）修改器获得所需的结果。您可以使用$1引用捕获组。

var result = "Cooker Works";
var searchterm = "cooker wor";

searchterm.split(" ").forEach(function(item) {
    result = result.replace(new RegExp(`(${item})`, 'ig'), "<strong>$1</strong>");
});

console.log(result)

您需要添加不区分大小写的修饰符。做这样的事情：

    var result = "Cooker Works" 
    var searchterm = "cooker wor";
    
    searchterm.split(" ").forEach(function (item) {
    result = result.replace(new RegExp('(' + item + ')', 'gi'),'<strong>$1</strong>');
    });
    console.log(result);
