[英]Javascript - Change text and color every 3 seconds
I need some help with a js code. 我需要有关js代码的帮助。 I've searched in other topics and i've tried some codes, but they didn't work.
我搜索了其他主题,并尝试了一些代码,但是它们没有用。 I need to change 2 text every 3 seconds and also the second text has to change their colour.
我需要每3秒更改2个文本,并且第二个文本也必须更改其颜色。
I used an jquery code, and the first part is done, but i don't know how to do the second. 我使用了一个jquery代码,并且第一部分已经完成,但是我不知道该怎么做。
This is my code 这是我的代码
<html>
<head>
<script src="js/jquery-2.1.4.min.js" type="text/javascript"></script>
<script>
$(function () {
cuenta = 0;
txtArray = ["TEXT1", "TEXT2"];
setInterval (function () {
cuenta++;
$("#titulos").fadeOut(100, function () {
$(this).text(txtArray [cuenta % txtArray.length]).fadeIn(100);
});
}, 3000);
});
</script>
<body>
<div>
<p id="titulos">TEXT1</p>
</div>
</body>
</html>
How can I change the colour of the second array? 如何更改第二个数组的颜色? Is there any other way to make this code with pure js, not with jquery?
还有其他方法可以用纯js(而不是jquery)制作此代码吗?
Thanks for all 谢谢大家
try this 尝试这个

var colors = ['blue', 'red', 'green', 'pink', 'yellow'];
var colorIndex = 1;
setInterval(function(){
$('#titulos').css('color', colors[colorIndex]);
if(colorIndex < colors.length)
colorIndex += 1;
else
colorIndex = 1;
}, 3000);
To change CSS with jQuery use .css('rule-name', 'value')
or .css({rule1: 'value', rule2: 'value'})
要使用jQuery更改CSS,请使用
.css('rule-name', 'value')
或.css({rule1: 'value', rule2: 'value'})
$(function() { cuenta = 0; txtArray = ["TEXT1", "TEXT2"]; setInterval(function() { cuenta++; $("#titulos").fadeOut(100, function() { $(this) .text(txtArray[cuenta % txtArray.length]) .css('color', cuenta % 2 == 0 ? 'red' : 'blue') .fadeIn(100); }); }, 3000); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div> <p id="titulos">TEXT1</p> </div>
Here you go: 干得好:
$(function () {
cuenta = 0;
txtArray = ["TEXT1", "TEXT2"];
setInterval (function () {
cuenta++;
$("#titulos").fadeOut(100, function () {
$(this).text(txtArray [cuenta % txtArray.length]).fadeIn(100);
if(cuenta % txtArray.length == 1)
{
$(this).css("color","red");
}
else
{
$(this).css("color","black");
}
});
}, 3000);
});
