[英]Adding callback to javascript while loop
I am trying to replicate a type-writer effect on a resume page of mine, and have if working except for one part: 我试图在我的简历页面上复制一个类型 - 作者效果,如果工作除了一部分:
while (i < tags.length) {
type(tags[i], content[i], 0, 50);
i++;
}
This is the function that writes out the lines, and it works correctly, except for the fact that it writes all of the lines at once. 这是写出行的函数,它正常工作,除了它一次写入所有行的事实。 I would like for it to write a single line, then move on to the next, and so on and so forth. 我想让它写一行,然后继续写下一行,依此类推。 I know the solution lies in adding a callback function in but I can't seem to get it to work right. 我知道解决方案在于添加一个回调函数,但我似乎无法让它正常工作。 Any help/advice would be appreciated. 任何帮助/建议将不胜感激。 Thanks! 谢谢!
A callback and a recursive function seems like the way to go 回调和递归函数似乎是要走的路
var type = function (target, message, index, interval, callback) {
if (index < message.length) {
$(target).append(message[index++]);
setTimeout(function () {
type(target, message, index, interval, callback);
}, interval);
} else {
callback();
}
}
var i = 0;
(function recursive() {
if (i < tags.length) {
type(tags[i], content[i], 0, 50, recursive);
i++;
}
})();
