我有一个基于shuffleLetters.js扰乱字母的功能。效果很好，但是我似乎无法排除嵌套在我要定位的类中的类。
因此，我想对菜单项中的字符进行加扰。因此，我给他们提供了.shuffle类并按如下所示调用函数：
$(function(){
var container = $(".shuffle")
container.shuffleLetters();
});
.shuffleLetters与插件互动的地方。问题在于它正在使嵌套在该菜单项中的所有字符变得混乱，这是我不想要的。
我已经了解了
.not方法，但是无法使其正常工作。这是我正在尝试的：
<li class="shuffle">title
<li class="no-shuffle">sub-title
</li>
</li>
然后我就这样写我的js（或每种可能的变体）：
$(function(){
var container = $(".shuffle").not('.no-shuffle')
container.shuffleLetters();
});
虽然这不起作用。
任何人都可以在这里向我指出正确的方向，使我的大脑耗时数小时。
一如既往，在此先感谢！
编辑：这是shuffleLetters.js：
(function($){
$.fn.shuffleLetters = function(prop){
var options = $.extend({
"step" : 8, // How many times should the letters be changed
"fps" : 25, // Frames Per Second
"text" : "", // Use this text instead of the contents
"callback" : function(){} // Run once the animation is complete
},prop)
return this.each(function(){
var el = $(this),
str = "";
// Preventing parallel animations using a flag;
if(el.data('animated')){
return true;
}
el.data('animated',true);
if(options.text) {
str = options.text.split('');
}
else {
str = el.text().split('');
}
// The types array holds the type for each character;
// Letters holds the positions of non-space characters;
var types = [],
letters = [];
// Looping through all the chars of the string
for(var i=0;i<str.length;i++){
var ch = str[i];
if(ch == " "){
types[i] = "space";
continue;
}
else if(/[a-z]/.test(ch)){
types[i] = "lowerLetter";
}
else if(/[A-Z]/.test(ch)){
types[i] = "upperLetter";
}
else {
types[i] = "symbol";
}
letters.push(i);
}
el.html("");
// Self executing named function expression:
(function shuffle(start){
// This code is run options.fps times per second
// and updates the contents of the page element
var i,
len = letters.length,
strCopy = str.slice(0); // Fresh copy of the string
if(start>len){
// The animation is complete. Updating the
// flag and triggering the callback;
el.data('animated',false);
options.callback(el);
return;
}
// All the work gets done here
for(i=Math.max(start,0); i < len; i++){
// The start argument and options.step limit
// the characters we will be working on at once
if( i < start+options.step){
// Generate a random character at thsi position
strCopy[letters[i]] = randomChar(types[letters[i]]);
}
else {
strCopy[letters[i]] = "";
}
}
el.text(strCopy.join(""));
setTimeout(function(){
shuffle(start+1);
},1000/options.fps);
})(-options.step);
});
};
function randomChar(type){
var pool = "";
if (type == "lowerLetter"){
pool = "abcdefghijklmnopqrstuvwxyz0123456789";
}
else if (type == "upperLetter"){
pool = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
}
else if (type == "symbol"){
pool = ",.?/\\(^)![]{}*&^%$#'\"";
}
var arr = pool.split('');
return arr[Math.floor(Math.random()*arr.length)];
}
})(jQuery);
最佳答案
尝试在.shuffle元素内的li span中包装文本节点“ title”
