1.1 link_to 一般形式: link_to "xxxx",{hash},{hash}
<%= link_to "Issues", {:controller => "issue", :action => "index"}, {:title => "Issues"} %>
link_to_unless_current 自动识别当前链接, 如果当前url和链接一样, 就只产生文本
事实上,html元素的属性都可以通过这样的方式来设置。比如添加一个click事件处理:
<%= link_to "Issues", {:controller => "issue", :action => "index"}, {:onclick => "alert(1)"} %>
<%= link_to "Issues", "index", {:onclick => "alert(1)"} %>
显示结果:"/xxxxx/controller/index?onclick=alert(1)" 所以如果第二个参数以字符串的形式给出,此时其后的参数,就变为queryString了。 那么如何实现又增加 click 事件处理,又增加url参数呢,很简单, 如下:
<%= link_to "Issues", {:controller => "issue", :action => "index", :param=value}, :onclick => "alert(1)" %>
结果为:
<a href="/issue/index?param=value" script_onclick="alert(1)">Issues</a>
