我有一个按钮,当我点击它时,我希望选中所有复选框。通过第二次单击,必须取消选中所有复选框。
<script type='text/javascript'>
$('#check_all').on("click", function(){ $('input[type="checkbox"]').click(); });
</script>
<%= form_tag save_share_patients_clinicdb_grp_pats_path, method: :post do %>
<%= hidden_field_tag 'to_share_group', @to_shr_group%>
<button type="button" id="check_all" class="btw"><%="Check all/Uncheck all"%></button>
<%@pat_ids.each do |pat_id|
%>
<%= check_box_tag "to_share_patients[]", pat_id.mk1%> <%=pat_id.mk1%>
<br/>
<%end%>
<%= button_tag :class => "btn btn-warning", :name => 'share' do %> <%= t "share" %> <% end %>
<%end%>
这里有些东西不起作用。你能帮帮我吗?
编辑:
$('#check_all').on("click", function(){ alert("aaa"); });
不会提醒任何事情

你试图在加载元素“check_all”之前调用“click”事件。因此,只有警报功能不起作用。
$(document).ready(function(){
$('#check_all').on("click", function(){ alert("hi") });
});
选择复选框,
$(document).ready(function(){
$('#check_all').on("click", function() {
// grouping all the checkbox using the classname
var checkboxes = $("class name for the checkbox");
// check whether checkboxes are selected.
if(checkboxes.prop("checked")){
// if they are selected, unchecking all the checkbox
checkboxes.prop("checked",false);
} else {
// if they are not selected, checking all the checkbox
checkboxes.prop("checked",true);
}
});
});

试试这个:
$('#check_all').on("click", function(){
var cbxs = $('input[type="checkbox"]');
cbxs.prop("checked", !cbxs.prop("checked"));
});
