我想实现JQ UIslider - 但我一直遇到问题,所以我希望有人可以帮助。JQuery滑块问题
我试图做到没有“滑块”按钮的JQUI图像。我可以得到这么多,但我无法让它“正常”工作。我的代码是这样的:
HTML:
<div id="scroll-pane" class="clearfix" >
<div id="pagination" class="clearfix"></div>
<div class="scroll-bar-wrap">
<div class="scroll-bar"></div></div>
</div>
CSS:
.scroll-bar { background-color:#00FFFF; width: 50px; height: 20px; }
#pagination { width: 2440px; float: left; }
#scroll-pane { overflow: auto; width: 99%; float:left; }
.scroll-bar-wrap { clear: left; padding: 0 4px 0 2px; margin: 0 -1px -1px -1px; background: #FFCC00; width: 400px; }
.scroll-bar-wrap .ui-slider { border:0; height: 2em; margin: 0 auto; background: #FF0000; width: 20px;}
和JQ是这样的:(顺便说一句我一句都没听懂了吧!)
$(document).ready(function() {
var scrollPane = $("#scroll-pane"),
scrollContent = $("#pagination");
var scrollbar = $(".scroll-bar").slider({
slide: function(event, ui) {
if (scrollContent.width() > scrollPane.width()) {
scrollContent.css("margin-left", Math.round(
ui.value/100 * (scrollPane.width() - scrollContent.width())
) + "px");
} else {
scrollContent.css("margin-left", 0);
}
}
});
//append icon to handle
var handleHelper = scrollbar.find(".ui-slider-handle")
.mousedown(function() {
scrollbar.width(handleHelper.width());
})
.mouseup(function() {
scrollbar.width("100%");
})
.append("<span class='ui-icon ui-icon-grip-dotted-vertical'></span>")
.wrap("<div class='ui-handle-helper-parent'></div>").parent();
//change overflow to hidden now that slider handles the scrolling
scrollPane.css("overflow", "hidden");
//size scrollbar and handle proportionally to scroll distance
function sizeScrollbar() {
var remainder = scrollContent.width() - scrollPane.width();
var proportion = remainder/scrollContent.width();
var handleSize = scrollPane.width() - (proportion * scrollPane.width());
scrollbar.find(".ui-slider-handle").css({
width: handleSize,
"margin-left": -handleSize/2
});
handleHelper.width("").width(scrollbar.width() - handleSize);
}
//reset slider value based on scroll content position
function resetValue() {
var remainder = scrollPane.width() - scrollContent.width();
var leftVal = scrollContent.css("margin-left") === "auto" ? 0 :
parseInt(scrollContent.css("margin-left"));
var percentage = Math.round(leftVal/remainder * 100);
scrollbar.slider("value", percentage);
}
//if the slider is 100% and window gets larger, reveal content
function reflowContent() {
var showing = scrollContent.width() + parseInt(scrollContent.css("margin-left"), 10);
var gap = scrollPane.width() - showing;
if (gap > 0) {
scrollContent.css("margin-left", parseInt(scrollContent.css("margin-left"), 10) + gap);
}
}
//change handle position on window resize
$(window).resize(function() {
resetValue();
sizeScrollbar();
reflowContent();
});
//init scrollbar size
setTimeout(sizeScrollbar, 10);//safari wants a timeout
});
#pagination的内容是“动态”生成的。我的问题是,.scroll-bar-wrap .ui-slider
不滑动(动画)。只是“触摸它”会过度快速地移动幻灯片内容,很难“恢复”。
我需要的是一个“简单滑块情境”,其中#页面向左/向右移动以在创建页面时显示/隐藏页码。有些东西告诉我JQUI代码是“过于复杂” - 我可能是错的 - 但到目前为止,这已经花费了很多时间在很简单的事情上 - 好吧,我不是JQ/JS类型的人,但是。 。JQUI示例link text正常工作,这是它的代码。我只是不希望背景/滑块按钮,因为他们有它。
