在这个页面http://317.masud-rana.com/apartments/中，我放了一个名为＆＃34;选择全部＆＃34;的复选框。在底部自动检查所有其他复选框。使用以下代码，它可能有我想要的但标记图标不显示。我怎么能解决它？
$(document).ready(function () {
$('#selecctall').click(function (event) { //on click
if (this.checked) { // check select status
$('.glemps-ckbx').each(function () { //loop through each checkbox
this.checked = true; //select all checkboxes with class "checkbox1"
});
} else {
$('.glemps-ckbx').each(function () { //loop through each checkbox
this.checked = false; //deselect all checkboxes with class "checkbox1"
});
}
});
});
修改：以下是Google地图的代码

只需在每个复选框上触发点击事件，如果尚未选中复选框。取消选中全选复选框时，撤消操作。
$('#selecctall').click(function () {
if (this.checked) {
$('.glemps-ckbx').each(function () {
// check if not already checked...
if (!this.checked) {
this.click();
}
});
} else {
$('.glemps-ckbx').each(function () {
if (this.checked) {
this.click();
}
});
}
});
