Javascript RoR:single:onclick上的多个远程函数调用
当用户单击按钮时,我有两种不同的方法要执行。我让它们分开工作,但当我尝试将两者结合起来时,会出现错误。我现在有两个Javascript RoR:single:onclick上的多个远程函数调用,javascript,ruby-on-rails,ajax,rjs,Javascript,Ruby On Rails,Ajax,Rjs,当用户单击按钮时,我有两种不同的方法要执行。我让它们分开工作,但当我尝试将两者结合起来时,会出现错误。我现在有两个 <%= image_tag('go_button.png', :id => "search_go_button", :class => "search_go_button", :onmouseover => "this.style.
<%= image_tag('go_button.png',

:before => "Element.show('search_spinner'); Element.hide('search_go_button');",
:success => "Element.hide('search_spinner'); Element.show('search_go_button');")
}}") %>
我基本上想把函数从底部添加到顶部。任何帮助都将不胜感激。本着UJS的精神(即使您在这里没有提供非javascript功能,您也可以从将javascript与erb分离中获益),我将使用并将其设置为行为。您需要先下载并包含lowpro.js文件
在.erb中,您只需使用图像标签:
<%= image_tag('go_button.png',
:id => "search_go_button",
:class => "search_go_button") %>
我们在所有行为中都使用它,它使代码更易于使用和管理
如果需要帮助整理AJAX调用,请发表评论。一种(快速)方法是尝试封装如下函数:
Event.addBehavior({
'#search_go_button:click' : function(e) {
// stuff you want to have happen in response to a click
},
'#search_go_button:mouseover' : function(e) {
// stuff you want to have happen in response to a mouseover
},
'#search_go_button:mouseout' : function(e) {
// stuff you want to have happen in response to a mouseout
}
});

也许您需要将变量传递到函数中,但这应该可以工作如果您可以粘贴错误,这将非常有帮助。
