这是我在设置hl=true和hl.fl=description时从solr获得的JSON数据。在这里，我获得了docs代码和highlighting代码。我需要解析highlighting标记，在<em>标记中的说明字段中突出显示“优雅”...每次动态生成UID_PK's(8252,8142)中的<highlighting>还有一件事。如果我将JSON数据作为

，请建议我该怎么做

$.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=20&q="+newquery+"&sort=price asc&hl=true&hl.fl=description&hl.usePhraseHighlighter=true&json.wrf=?", function(newresult){

并将其解析为

$.each(newresult.response.docs, function(i,item){

和

 $.each(newresult.highlighting, function(i,hitem){

Answer 1

假设响应始终是文本，并且只有要突出显示的元素包含在<em>标记中，并且只有其中一个，您可以这样做：

var highlight = {};

$.each(newresult.highlighting, function(i, hitem){
    var match = hitem.description[0].match(/<em>(.*?)<\/em>/);
    highlight[i] = match[1];
});

$.each(newresult.response.docs, function(i, item){
    var word = highlight[item["UID_PK"]];
    var result = item.description.replace(new RegExp(word, 'g'), '<em>' + word + '</em>');
    // do something with the result
});

仅当word不包含任何特殊正则表达式字符（in which case you'd have to escape them）时才有效。如果您知道要突出显示的单词仅在搜索结果中出现一次，则不必使用正则表达式：

item.description.replace(word, '<em>' + word + '</em>');
