javascript - 使文本看起来像用打字机打字一样

Question

如何使文本看起来好像是用 JavaScript 和 jQuery 一次输入一个字母？

我尝试隐藏内容，然后通过多次调用一次显示一个字母setTimeout()，但这似乎效率很低。

任何人都知道更好的方法或可以模拟这种效果的脚本或插件吗？

我也想要一个闪烁的光标！

Answer 1

jQuery Typewriter available here: https://github.com/chadselph/jquery-typewriter

Here is an example of how it works:

  $('.someselector').typewrite({
    'delay': 100, //time in ms between each letter
    'extra_char': '', //"cursor" character to append after each display
    'trim': true, // Trim the string to type (Default: false, does not trim)
    'callback': null // if exists, called after all effects have finished
});

Answer 2

here is an example I made

(function($){$.fn.typeWrite=function(s){
        var o={content:$(this).text(),delay:50,t:this,i:0};
        if(s){$.extend(o,s);}o.t.text('');
        var i=setInterval(function() {
            o.t.text(o.t.text()+o.content.charAt(o.i++));    
            if(o.i==o.content.length){clearInterval(i);}}
        ,o.delay);
      return o.t;  
    };})(jQuery);
    
    $('#test').typeWrite({content:'The stuff to type'});
