使用格式输入文字效果:跳过HTML标签,但不要删除 [英] Typing text effect with formatting: skip HTML tags, but don't remove
问题描述
我试图提供一种简单的方法来获得输入文本效果,但也可以允许使用HTML标记。我有一些可行的代码,但我发现标签被认为是文本的一部分。
例如,如果文本是任何人都是< b>真棒< / b>
,我看到当它到达大胆的部分时:
<
< b> b>
< b> a
< b> aw
< b> awe
< b> awes
< b> aweso
< b< ; b> awesom
< b>真棒
< b>真棒<
< b>真棒< /
< b>真棒< / b
< b> awesome< / b>
如何跳过html节点而不从字符串中移除它们?我想保持格式化工作。
以下是我迄今为止所做的:
< div id =foo>< / div>
$ .fn.typer = function(text,options){
options = $ .extend({},{
delay:1000,
duration:1000,
easing:'linear ',
endless:false
},options);
var elem = $(this);
(function loop(i) {
var e = typeof text ==='string'? text:text [i];
//带html标签,可能有帮助
// e.replace(/(<。*?>)/ ig,)
$({len:0} ).delay(options.delay).animate({len:e.length},{
duration:options.duration,
easing:options.easing,
step:function(now) {
var pos = Math.ceil(now),
char = e.substr(pos,0);
elem.html(e.substr(0,pos));
$,
complete:function(){
i ++;
if(i === text.length&&!options.endless){
return;
} else if(i === text.length){
i = 0;
}
loop(i);
}
});
})(0);
};
$('#foo')。typer(['< i>任何人< / i>< u>< / u>< b>真棒< /> ;!', 'Foo bar。']);

示例没有 jQuery
的动画功能。
如果您有任何改进,请在此分享!
c $ c> e ,使用:
e = $(e).text();
这个假设e已知包含HTML开头。如果它可能包含纯文本,请先将它包装在DIV中:
e = $('< div> + e + '< / DIV>'。)文本();
否则,jQuery会尝试将其解释为选择器。
I am trying to provide a simple way to get a typing text effect, but with the possibility to allow HTML tags too. I have some code that works, but I see the tags are being considered part of the text.
For example, if The text is "Anyone is <b>awesome</b>
, I see the following when it reaches the bold part:
<
<b
<b>
<b>a
<b>aw
<b>awe
<b>awes
<b>aweso
<b>awesom
<b>awesome
<b>awesome<
<b>awesome</
<b>awesome</b
<b>awesome</b>
How can I skip html nodes without removing them from string? I want to keep the formatting working.
Here's what I've done so far:
<div id="foo"></div>
$.fn.typer = function (text, options) {
options = $.extend({}, {
delay: 1000,
duration: 1000,
easing: 'linear',
endless: false
}, options);
var elem = $(this);
(function loop(i) {
var e = typeof text === 'string' ? text : text[i];
// strip html tags, might be helpful
// e.replace(/(<.*?>)/ig,"")
$({len: 0}).delay(options.delay).animate({len: e.length}, {
duration: options.duration,
easing: options.easing,
step: function (now) {
var pos = Math.ceil(now),
char = e.substr(pos, 0);
elem.html(e.substr(0, pos));
},
complete: function () {
i++;
if (i === text.length && !options.endless) {
return;
} else if (i === text.length) {
i = 0;
}
loop(i);
}
});
})(0);
};
$('#foo').typer(['<i>Anyone</i> <u>is</u> <b>awesome</>!', 'Foo bar.']);

Update
example without jQuery
's animate-function.
If you've any improvements, share them here!
To strip the tags from e
, use:
e = $(e).text();
This assumes e is known to contain HTML to begin with. If it might contain plain text, wrap it in a DIV first:
e = $('<div>'+e+'</div>').text();
Otherwise, jQuery will try to interpret it as a selector.
