count the number of existing tabs in jquery?
提问by Robert Harvey
I'm using a dynamic jQuery tab widget to add/remove tabs generated programmatically.
我正在使用动态 jQuery 选项卡小部件来添加/删除以编程方式生成的选项卡。
How do I check through jQuery and count how many existing tabs are present in the widget?
如何检查 jQuery 并计算小部件中存在多少个现有选项卡？
I'm using this code, but it doesn't work:
我正在使用此代码，但它不起作用：
$('#container-1 > ul').tabs('add', tabName, name);
var newTab;
if ($('#container-1 > li').size() < 0) {
newTab = $(tabName).css('display', 'block')
} else {
newTab = $(tabName).css('display', 'none');
}
newTab.html('<iframe src="ViewPatient.aspx?pname=' + name
+ '" width="100%" frameborder="0" scrolling="no" height="300"></iframe>');

Just use the below code
只需使用下面的代码
$('#selector >ul >li').size();
where "#selector" is the selector you have used to create the tabs.
其中“#selector”是您用于创建选项卡的选择器。
UPDATE
更新
size()function doesn't exist any more, now the solution is:
size()函数不再存在，现在解决方案是：
$('#selector >ul >li').length;

var tabCount = $(tabContainer).tabs("length");
