我在JSFiddle上使用了Tats发布的一些代码。它适用于JSFiddle:http://jsfiddle.net/FWWEn/397/ 但不是在我的HTML页面上。我在这些脚本标记之间插入了函数:
script type='text/javascript' src='http://code.jquery.com/jquery.min.js'
并将其插入/html
标记之前的.asp文件的末尾。
我插入的h1
标记无效。为什么不呢?
<body>
<h1 align="center" bgcolor="#FFFFCC" width="800" class="style33" > Hours next week are 8:30am - 6:30pm. </h1>
</body>
<script type='text/javascript' src='http://code.jquery.com/jquery.min.js'>
function($) {
$.fn.textWidth = function(){
var calc = '<span style="display:none">' + $(this).text() + '</span>';
$('body').append(calc);
var width = $('body').find('span:last').width();
$('body').find('span:last').remove();
return width;
};
$.fn.marquee = function(args) {
var that = $(this);
var textWidth = that.textWidth(),
offset = that.width(),
width = offset,
css = {
'text-indent' : that.css('text-indent'),
'overflow' : that.css('overflow'),
'white-space' : that.css('white-space')
},
marqueeCss = {
'text-indent' : width,
'overflow' : 'hidden',
'white-space' : 'nowrap'
},
args = $.extend(true, { count: -1, speed: 1e1, leftToRight: false }, args),
i = 0,
stop = textWidth*-1,
dfd = $.Deferred();
function go() {
if(!that.length) return dfd.reject();
if(width == stop) {
i++;
if(i == args.count) {
that.css(css);
return dfd.resolve();
}
if(args.leftToRight) {
width = textWidth*-1;
} else {
width = offset;
}
}
that.css('text-indent', width + 'px');
if(args.leftToRight) {
width++;
} else {
width--;
}
setTimeout(go, args.speed);
};
if(args.leftToRight) {
width = textWidth*-1;
width++;
stop = offset;
} else {
width--;
}
that.css(marqueeCss);
go();
return dfd.promise();
};
$('h1').marquee();
})(jQuery);
</script>
答案 0 :(得分:0)
使用带有src属性的脚本标记将不会解释其中的代码,除非存在源问题。
所以只需要包含这样的jquery:
<script type='text/javascript' src='http://code.jquery.com/jquery.min.js'></script>
然后使用新的脚本标记来包含您的代码:
<script>
function($) {
$.fn.textWidth = function(){
var calc = '<span style="display:none">' + $(this).text() + '</span>';
$('body').append(calc);
var width = $('body').find('span:last').width();
$('body').find('span:last').remove();
return width;
};
$.fn.marquee = function(args) {
var that = $(this);
var textWidth = that.textWidth(),
offset = that.width(),
width = offset,
css = {
'text-indent' : that.css('text-indent'),
'overflow' : that.css('overflow'),
'white-space' : that.css('white-space')
},
marqueeCss = {
'text-indent' : width,
'overflow' : 'hidden',
'white-space' : 'nowrap'
},
args = $.extend(true, { count: -1, speed: 1e1, leftToRight: false }, args),
i = 0,
stop = textWidth*-1,
dfd = $.Deferred();
function go() {
if(!that.length) return dfd.reject();
if(width == stop) {
i++;
if(i == args.count) {
that.css(css);
return dfd.resolve();
}
if(args.leftToRight) {
width = textWidth*-1;
} else {
width = offset;
}
}
that.css('text-indent', width + 'px');
if(args.leftToRight) {
width++;
} else {
width--;
}
setTimeout(go, args.speed);
};
if(args.leftToRight) {
width = textWidth*-1;
width++;
stop = offset;
} else {
width--;
}
that.css(marqueeCss);
go();
return dfd.promise();
};
$('h1').marquee();
})(jQuery);
</script>
