Question

我已经制作了如下表格。

<div class="grid_top_button">
        <div class="left_top_curve">
                &nbsp;</div>
        <div class="right_top_curve">
                &nbsp;</div>
        <input name="input" type="button" id="addSelected" name="addSelected" class="section_btn"
                value="Link" />
</div>
<table id="LstDocTemp" border="0" cellpadding="0" cellspacing="0" class="instruction_grid">
    <tr>
        <th align="left" class="ins_sl_no">
                        Sl No.
                </th>
                <th align="left" class="selct_column">
                        <input type="checkbox" id="chkSelectAll" name="chkSelectAll" />
                </th>
                <th align="left" class="doc_title_1">

                </th>
                <th align="left" class="description">

                <th align="left" class="part_no">

        </tr>
        <% int slNo = 1; %>
        <%foreach (var item in Model)
            { %>
        <tr id="<%= Html.Encode(item.DocId) %>">
                <td>
                        <%= slNo %>
                </td>
                <td>
                        <input type="checkbox" name="chkItem" class="chk" id="chkbox_<%=Html.Encode(item.DocId) %>" />
                </td>
                <td>

                </td>
                <td>
                        <%= Html.Hidden("DocDesc", item.DocDesc)%>
                        <%= Html.Encode(item.DocDesc) %>
                </td>
                <td class="dark_highlight">
                        <%= Html.Hidden("DocRevision", item.DocRevision)%>
                        <%= Html.Encode(item.DocRevision) %>
                </td>

                </td>
        </tr>
        <%slNo++;
            } %>
</table>

我需要实现以下目标：

通过选中复选框（name =“chkItem”）在控制器中为所选行执行操作。
选中复选框（name =“chkSelectAll）时，选中/取消选中复选框（name =”chkItem“）。
选中全部选中chkSelectAll复选框后，取消选中任何人都应该取消选中chkSelectAll复选框。

Answer 1

首先，你可以这样做......

if($('.chk').is(':checked')){
 //perform the action in controller
}

第二点 -

$(".selectAll").click(function(){
  var checked = $("#selectall").attr("checked");
  $(".chk").attr("checked",checked);
}

第三点 -

$(".chk").click(function(){
 var checkedBoxes= $(".selectone").map(function(){ return jQuery(this).attr("checked");}).get();
 var flg = true;
 if(jQuery.inArray(false, net)){
   flg= false;
 }
 $("#selectall").attr("checked",flg);
});

Answer 2

$("#selectall").click(function(){
    var checked = $("#selectall").attr("checked");
    $(".selectone").attr("checked",checked);
});

用于设置全选

 $(".selectone").click(function(){
   var net = $(".selectone").map(function(){ return jQuery(this).attr("checked");}).get();
   var flg = true;
   if(jQuery.inArray(false, net)){
     flg= false;
   }
   $("#selectall").attr("checked",flg);
 });
