最近是累了点，懒了点。
- 一个div元素，点击，页面外的元素，隐藏此div。
1: $(document).mouseup(function (e)
2: {
3: var container = $("YOUR CONTAINER SELECTOR");
4:
5: if (!container.is(e.target) // if the target of the click isn't the container...
6: && container.has(e.target).length === 0) // ... nor a descendant of the container
7: {
8: container.hide();
9: }
10: });
- jquery.bxslider 是一个很不错的插件。
目前的版本是4+，使用过程中，碰到了几个bug.
如果刚好slider正在切换[gotoprev,gotonext]的时候，进行重绘[redraw]，会造成slider停止工作。修复代码如下：
修改前：
1: el.redrawSlider = function () {
2: // resize all children in ratio to new screen size
3: slider.children.add(el.find('.bx-clone')).width(getSlideWidth());
4: // adjust the height
5: slider.viewport.css('height', getViewportHeight());
6: // update the slide position
7: if (!slider.settings.ticker) setSlidePosition();
8: // if active.last was true before the screen resize, we want
9: // to keep it last no matter what screen size we end on
10: if (slider.active.last) slider.active.index = getPagerQty() - 1;
11: // if the active index (page) no longer exists due to the resize, simply set the index as last
12: if (slider.active.index >= getPagerQty()) slider.active.last = true;
13: // if a pager is being displayed and a custom pager is not being used, update it
14: if (slider.settings.pager && !slider.settings.pagerCustom) {
15: populatePager();
16: updatePagerActive(slider.active.index);
17: }
18: }
修改后：
1: el.redrawSlider = function () {
2: if (slider.working) {
3: // Wait 'speed' amount of time before redrawing
4: setTimeout(function () { el.doRedrawSlider(); }, slider.settings.speed);
5: } else {
6: // Redraw immediately
7: el.doRedrawSlider();
8: }
9: };
10:
11: el.doRedrawSlider = function() {
12: // resize all children in ratio to new screen size
13: slider.children.add(el.find('.bx-clone')).width(getSlideWidth());
14: // adjust the height
15: slider.viewport.css('height', getViewportHeight());
16: // update the slide position
17: if (!slider.settings.ticker) setSlidePosition();
18: // if active.last was true before the screen resize, we want
19: // to keep it last no matter what screen size we end on
20: if (slider.active.last) slider.active.index = getPagerQty() - 1;
21: // if the active index (page) no longer exists due to the resize, simply set the index as last
22: if (slider.active.index >= getPagerQty()) slider.active.last = true;
23: // if a pager is being displayed and a custom pager is not being used, update it
24: if (slider.settings.pager && !slider.settings.pagerCustom) {
25: populatePager();
26: updatePagerActive(slider.active.index);
27: }
28: };
slider元素中，如果有img或者iframe无法正常加载，会引发slider无法正常工作。
修复前：
1: var loadElements = function (selector, callback) {
2: var total = selector.find('img, iframe').length;
3: if (total == 0) {
4: callback();
5: return;
6: }
7: var count = 0;
8: selector.find('img, iframe').each(function () {
9: $(this).one('load', function () {
10: if (++count == total) callback();
11: }).each(function () {
12: if (this.complete) $(this).load();
13: });
14: });
15: }
修复后：
1: var loadElements = function (selector, callback) {
2: var total = selector.find('img, iframe').length;
3: if (total == 0) {
4: callback();
5: return;
6: }
7: var count = 0;
8: selector.find('img, iframe').each(function () {
9: $(this).one('load', function () {
10: if (++count == total) callback();
11: }).one('error', function() {
12: if (++count == total) callback();
13: }).each(function () {
14: if (this.complete) $(this).load();
15: });
16: });
17: }
