javascript - jQuery:将数组项与文本匹配>从数组中删除项

Question

如何将数组项与文本进行匹配并使用找到的项(以文本格式设置并从数组列表中删除)？

我不知道数组，也不知道文本。但是当文本中包含数组项时，那就聚会吧!

var arrString = 'apple, banana, monkey, sugar',
    text = "This a nice  monkey  zoo with  banana  trees.";

var arr = arrString.split(", ");

var arrMatch = "";

for(var i=0;i<arr.length;i++){
    if(text.search(arr[i])!=-1){
        arrMatch = arr[i];

        //format found item in text
        var text = text.replace(arrMatch, '<b>'+arrMatch+'</b>');

        //Remove found item from array <<<<<< Needs a fix
        if ( i !== -1 ) arr.splice(i, 1);
    }
}

if(arrMatch !== "") {
    $("body").append(arrString + '<br><br>The text contains the array item(s) "'+ arrMatch +'".');
}

var arrLeft = arr.join(", ");

$("body").append("<br><br><hr /><br>" + text + "<br><br>These array items are left: " + arrLeft);

尝试

for(var i=0;i<arr.length;i++){
    if(text.search(arr[i])!=-1){
        arrMatch = arr[i];
        text = text.replace(arrMatch, '<b>'+arrMatch+'</b>'); 
        //Remove found item from array <<<<<< Needs a fix
        if ( i !== -1 ){ arr.splice(i, 1); i--;}//decrement the index
    }
}
