我想在循环遍历 div 元素时检测 span 元素,即
<div class="example">
These are some <span id ="special" class="anime">special</span> words
that should be faded in one after the other.
</div>
使用javascript我拆分单词并将它们一一淡入即
JS:
function doSomething(spanID) {
alert(spanID);
}
var $el = $(".example:first"), text = $.trim($el.text()),
words = text.split(" "), html = "";
for (var i = 0; i < words.length; i++) {
html += "<span>" + words[i] + ((i+1) === words.length ? "" : " ") + "</span>";
};
$el.html(html).children().hide().each(function(i){
// if special span is detected
// get the span id pass it to doSomething function
$(this).delay(i*200).fadeIn(700);
});
$el.find("span").promise().done(function(){
$el.text(function(i, text){
return $.trim(text);
});
});

一切正常,只是我需要检测任何特殊的跨度,以便我可以对它们做一些事情,然后 for 循环应该继续做它 deos 的事情。谢谢
