$("span:contains('FIND ME')")

ETA：

The contains selector is nice, but filtering a list of spans if probably quicker: http://jsperf.com/jquery-contains-vs-filter

包含选择器很好，但如果可能更快，则过滤一个跨度列表：http：//jsperf.com/jquery-contains-vs-filter

$("span").filter(function() { return ($(this).text().indexOf('FIND ME') > -1) }); -- anywhere match
$("span").filter(function() { return ($(this).text() === 'FIND ME') }); -- exact match

#2

Use contains:

使用包含：

$("span:contains('FIND ME')")

#3

I think this will work

我认为这会奏效

var span;
$('span').each(function(){
  if($(this).html() == 'FIND ME'){
    span = $(this);
  }
});

By the way, if you'd like to use this with a variable, you'd do it this way:

顺便说一句，如果您想将它与变量一起使用，您可以这样做：

function findText() {
    $('span').css('border', 'none');  //reset all of the spans to no border
    var find = $('#txtFind').val();   //where txtFind is a simple text input for your search value
    if (find != null && find.length > 0) {
        //search every span for this content
        $("span:contains(" + find + ")").each(function () {
            $(this).css('border', 'solid 2px red');    //mark the content
        });
     }
}
