Question

我想在标题中替换“the”，“and”等关键字，并将其替换为标题标记中的span。

例如：

<h2>This is the heading</h2>

成为

<h2>This is <span>the</span> heading</h2>

感谢您的帮助

我找到了适合我想要的东西：

$(function() {
$('h2').each(function(i, elem) {
    $(elem).html(function(i, html) {
        return html.replace(/the/, "<span>the</span>");
    });
});
});

Answer 1

仅限PHP的解决方案（不使用正则表达式）：

$string = "<h2>This is the heading</h2>";
$toReplace = array("the", "and");

$replaceTo = array_map(function ($val) { return "<span>$val</span>"; }, $toReplace);
$newString = str_replace($toReplace, $replaceTo, $string);

print $newString; // prints as expected: <h2>This is <span>the</span> heading</h2>

Answer 2

此代码将帮助您实现并动态扩展您的文字：

$special_words = array("the", "and", "or") ;
$words = implode("|", $special_words) ;

$string = "<h2>This is the heading</h2>" ;
$new = preg_replace("/({$words})/i", "<span>$1</span>", $string) ;

echo $new ;

Answer 3

使用regexp非常简单，此示例仅使用一个关键字，因为多个关键字使用数组。

$string = "<h2>This is the heading</h2>";
$string = preg_replace("/(the|end)/", "<span>$1</span>", $string);

用php或jquery替换标题中的关键字？
