Question

我是Javascript和jQuery的新手。我在段落中有一个文本。我想用黄绿色突出显示以大写字母开头的所有单词。这是我的源代码。但它不能正常运作。

    <!DOCTYPE html>
    <html>
    <head>
<style>
.mycls {background-color:yellowgreen}
</style>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
    <script>
    $(document).ready(function(){
        var str = $(p).text();

                words = str.split(' ');

                for (var i = 0; i < words.length; i++) {
                    var w = words[i].split('');

                    if (w.charAt(0) === w.charAt(0).toUpperCase()) {
                        $(this).addClass("mycls");
                    }

                 //   words[i] = letters.join('');
                }
    });
    </script>
    </head>
    <body>

    <p>President of USA Barack Obama is ...</p>

    </body>
    </html>

谢谢大家！

...
Dim xpathToExtractRow As String, XMLNamespaces As String
Dim dom As DOMDocument60

xpathToExtractRow = "/doc:cqresponse/doc:rows/doc:row"
XMLNamespaces = "xmlns:doc='http://ibm.com/rational/cqweb/v7.1'"

Set dom = New DOMDocument60
dom.Load ("C:\ABC.xml")
dom.setProperty "SelectionNamespaces", XMLNamespaces
...

＆＃13;

$('p').each(function(){ // to each <p>
  r = /[A-Z]\w*/g; // big letter with word symbols, global search
  function f(x){
    return '<span class="y">'+x+'</span>' // rewrited
  }
  h = $(this).html(); //get
  h = h.replace(r,f); //replace
  $(this).html(h); //set
}) //done

＆＃13;

.y {
  background-color: yellowgreen;
}

试试这个：

<p>President of USA Barack Obama is ...</p>
<style>
.highlighted
{
 background-color: yellow;
}
</style>
<script>
var split = $('p').text().split("");
var upperCase= new RegExp('[A-Z]');
$.each(split,function(i)
{
  if(split[i].match(upperCase))
  {
    $('p').html($('p').html().replace(split[i],'<span class=\"highlighted\">' + split[i] + '</span>')); 
  }
});
</script>
