[英]How to select the check box on button click
In the users tab there are some rows having check boxes. 在“用户”选项卡中,有些行具有复选框。 So if more than 2 check boxes are selected then a button named group appears. 因此,如果选中了两个以上的复选框,则会出现一个名为group的按钮。
Now when group button is clicked then then it will ask for a name and after pressing the ok button on the right side in the group table a group is created. 现在,当单击组按钮时,它将要求输入名称,并在组表的右侧按下确定按钮后,将创建一个组。 For example select 1st and last row and click the group button. 例如,选择第一行和最后一行,然后单击组按钮。 A dialog box appears asking to enter name. 出现一个对话框,要求输入名称。 Enter test in the input field, after that in the right side group table test appears(please see the screenshot). 在输入字段中输入测试,然后在右侧组表中显示测试(请参见屏幕截图)。
Now my question: is if I click the test(group name) now then on the left side the checkboxes will be selected. 现在我的问题是:如果我现在单击测试(组名),则在左侧的复选框将被选中。 So in my case 1st check box and last check box will be selected. 因此,在我的情况下,第一个复选框和最后一个复选框将被选中。 Please tell me how to do this. 请告诉我该怎么做。 This is the fiddle 这是小提琴

var sCheckbox = new Array();
$('#mytable tr').find('input[type="checkbox"]:checked').each(function(i) {
sCheckbox.push($(this).attr("data-id"));
});
var ds = (sCheckbox.length > 0) ? sCheckbox.join(",") : "";
Modify this line 修改这行
$tr.append("<td data-selected='"+ds+"'>" + creat_group + "</td>");
Add this event 添加此活动
$(document).on('click','#groupTable tr td',function () {
var dataids = $(this).attr("data-selected").split(",");
$('#mytable tr').find('input[type="checkbox"]').attr("checked",false);
$(dataids).each(function(key,dataid) {
$('#mytable tr').find('input[data-id="'+dataid+'"]').attr("checked",true);
})
});
Edit 编辑
Add this data-id="mytr' + val + '"
in checkbox
element 在checkbox
元素中添加此data-id="mytr' + val + '"
$tr.append('<td class=\"cb\"><input data-id="mytr' + val + '" type=\"checkbox\" value=\"yes\" name="mytr' + val + '" unchecked ></td>');
