我想点击checkbox
上的任意位置选中row
,包括复选框。如果在enable
中选中了任何一个复选框,我希望disable
和button
tbody
。
点击Selectall checkbox
需要选择所有行并启用按钮。
我在选择和取消选中复选框时仍有一些问题。
我给出了迄今为止我尝试过的示例,但我想将其视为非重复代码。如何才能使这段代码变得简单而有效?

进行一些更改,使复选框对齐。有关详细信息,请参阅代码注释:
如果代码段不起作用
var testing = function (e) {
var submit = $('#percentage_submit_button');
var checkbox = $(this);
if ($(this).is('tr')) {
checkbox = $(this).find('input[type="checkbox"]');
}
submit.prop('disabled', true); // Disable submit button
checkbox.prop('checked', !checkbox.is(':checked')); // Change checked property
if (checkbox.hasClass('all')) { // If this is "all"
$('.v_checkbox:not(.all)').prop('checked', checkbox.is(':checked')); // Set all other to same as "all"
if (checkbox.is(':checked')) { // change colour of "all" tr
checkbox.closest('tr').addClass('diff_color');
} else {
checkbox.closest('tr').removeClass('diff_color');
}
}
var blnAllChecked = true; // Flag all of them as checked
$('.v_checkbox:not(.all)').each(function() { // Loop through all checkboxes that aren't "all"
if ($(this).is(':checked')) {
$(this).closest('tr').addClass('diff_color');
submit.prop('disabled', false); // enable submit if one is checked
} else {
$(this).closest('tr').removeClass('diff_color');
blnAllChecked = false; // If one is not checked, flag all as not checked
}
});
if (blnAllChecked) {
$('.v_checkbox.all').closest('tr').addClass('diff_color');
$('.v_checkbox.all').prop('checked', true);

$('.v_checkbox.all').prop('checked', false);
}

我在select all input <input type="checkbox" id="v_checkbox_all" class="v_checkbox" />Select</th>
首先检查选择所有输入。将它的状态应用于每个输入,然后使用.each()循环遍历每一行并应用行样式。
在这里演示:JSfiddle
$(document).ready(function () {
var testing = function (e) {
var submit = $('#percentage_submit_button');
var checked = $(this).find('input[type="checkbox"]');
var checkedAll = $('#v_checkbox_all');
var isAllChecked = false;
submit.prop('disabled', true);
checked.prop('checked', !checked.is(':checked'));
$(this).prop('checked', !$(this).is(':checked'));
var checkedCount = $('.v_checkbox:checked').not('#v_checkbox_all').length;
var totalCount = $('.v_checkbox').not('#v_checkbox_all').length;
if (checked.prop('id') === 'v_checkbox_all') {
isAllChecked = true;
} else {
if (checked.prop('id') === 'v_checkbox_all' || checkedCount === totalCount) {
checkedAll.prop('checked', true);
} else {
checkedAll.prop('checked', false);
}
}
if (isAllChecked) {
if (checkedAll.is(':checked')) {
$('.v_checkbox').each(function () {
$(this).prop('checked', true);
});
} else {
$('.v_checkbox').each(function () {
$(this).prop('checked', false);
});
}
}
$('.v_checkbox').each(function () {
if ($(this).is(':checked')) {
$(this).closest('tr').addClass('diff_color');
submit.removeAttr('disabled');
} else {
$(this).closest('tr').removeClass('diff_color');
}
});
};
$(document).on('click', '.pv', testing);
$(document).on('click', 'input[type="checkbox"]', testing);
$('#percentage_submit_button').prop('disabled', true);
});

要选择所有复选框,请使用以下代码:
$('.v_checkbox').change(function(){
$('.v_checkbox').each(function(){
$(this).prop( "checked", true );
})
;
})
