我正在尝试使用typed.js在此文本输入框中提供示例城市。我的目标是让它在点击时完全停止动画。我该怎么做呢？
这是我的尝试。
JS：
$(document).ready(function(){
$(function()
{
$("#input_text").typed(
{
strings: ["^2000", "New York City^2000", "Berlin^2000", "London^2000", "Hong Kong^2000", "Chicago^2000", ""],
typeSpeed: 50
});
});
$( "#input_text" ).click(function()
{
$( "#input_text" ).stop();
});
});
我对javascript很陌生，所以你能告诉我如何实现我的目标吗？

来自源代码：
开始＆amp;停止当前不工作
所以如果你需要手动停止一个我不建议你的技巧是重新映射外部这个插件使用的超时功能或者插件本身（这是我的建议）。
要在外部操作超时，您可以执行以下操作：
var _setTimeout;
var _clearTimeout;
var _pauseOn;
_setTimeout = window.setTimeout;
_clearTimeout = window.clearTimeout;
window.setTimeout = function(code, delay) {
return _setTimeout(function () {
if (_pauseOn == true) {
return;
}
code();
}, delay);
};
window.clearTimeout = function(intervalId) {
if (_pauseOn == true) {
return;
}
_clearTimeout(intervalId);
};
function pauseTimer() {
_pauseOn = true;
}
........
$( "#input_text" ).click(function() {
pauseTimer();
});
在下面的代码段中。
//-----------------------
// avoid or fork
//
var _setTimeout;
var _clearTimeout;
var _pauseOn;
_setTimeout = window.setTimeout;
_clearTimeout = window.clearTimeout;
window.setTimeout = function(code, delay) {
return _setTimeout(function () {
if (_pauseOn == true) {
return;
}
code();
}, delay);
};
window.clearTimeout = function(intervalId) {
if (_pauseOn == true) {
return;
}
_clearTimeout(intervalId);
};
function pauseTimer() {
_pauseOn = true;
}
//-----------------------
// avoid or fork
//
$(function () {
$("#input_text").typed({
strings: ["^2000", "New York City^2000", "Berlin^2000", "London^2000", "Hong Kong^2000", "Chicago^^2000", ""],
typeSpeed: 50
});
$( "#input_text" ).click(function() {
pauseTimer();
$( "#input_text").val('');
});
});input{
font-size:3em;
}

你可以像
一样替换它 $('#input_text').on('click', function(e){
$(this).data('typed').reset();
$('#input_text').replaceWith('<input type="text" name="q" size="25" id="input_text" value=""/>');
$("#input_text").focus();
});
