javascript 好用及常用函数(ruby)
1.js延时与动态显示
new Ajax.Updater('yourid', 'rails/info/properties', {
method: 'get',
onFailure: function() {Element.classNames('yourid').add('failure')},
onComplete: function() {new Effect.BlindDown('yourid', {duration: 0.25})}
//有慢慢向下效果
});
} else {
new Effect[Element.visible('yourid') ?
'BlindUp' : 'BlindDown']('yourid', {duration: 0.25}); # 根据判断有向上或向下效果
}
延时用 duration: 0.25 delay:3
2.显示与隐藏层 结合rial 的Ajax 有londing 效果
<%= link_to_remote "Say Hello",
:url => tasks_url(:action => 'hello'),
:loading => "Element.show('loading')",
:complete => "Element.hide('loading')" %>
3.延时
page.delay(0.3) do
page.replace_html 'countdown', '<div id="countdownGO">GO!</div>'
page.visual_effect :puff, 'countdown', :duration => 0.5
page.delay(0.3) do
page.visual_effect :fade, 'profile-indicator' #淡淡消失
page.visual_effect :squish, "tosquish" #发出咯吱的声音失
page.visual_effect:highlight, "important", :duration => 1.5#高亮
page.replace_html 'info', :partial => 'info/test'
end
end
