显示在引导导航栏中添加时动态添加的导航链接 [英] show dynamically added navlinks when added in bootstrap navbar
问题描述
我是新的Bootstrap,并且似乎无法想出这一点,我有navbar被用作Bootstrap的javascript标签功能,它可以动态添加和删除导航链接,我使用图像而不是默认导航链接,我的问题是当我添加动态导航链接,它应该成为活动类,并显示其相关内容,目前我必须点击使其活动,如果我删除任何导航链接,内容是否有一种方法来实现此功能
html是:
< ul id =nav-tabsdata-tabs =tabs>
< li class =test>< img src =assets / img / button_home_selected3.pngclass =hoverwidth =83/>< span& < / a> < / li>
< / ul>
点击此按钮时添加标签:
< a href =#class =plustitle =点击添加标签>< img src =assets / img / icon_plus.png />< / a>
li使用
添加 var counter = 1;
$('。plus')。click(function(e){
e.preventDefault();
var li_count = $('#nav-tabs')。find .test)。length;
if(li_count <= 3)
if(counter< = 3){
$('#nav-tabs')。append('< ; li class =test>< img src =assets / img / button_home_selected3.pngclass =hoverwidth =83/>< span>首页< / span>< / a> < button type =buttonclass =close>& times;< / button>< / div>< / a>< / li>');
} else {alert (Only 3 Tabs Allowed!)};
/ p>
标签中的活动类使用
切换。 $导航标签)。on(click,a,function(e){
e.preventDefault();
$(this).tab('show');
$('li.test')。每个(function(){
if($(this).hasClass('active'))
{
//活动类应用
$(this).children()。children()。closest(img)。attr(src,assets / img / button_home_selected3.png);
$(this).find(button)。show();
}
else
{
$(this).children()。children()。closest(img)。attr(src,assets / img / button_home_plain2.png);
$(this).find(button)。hide();
}
});
li在新导航链接中使用按钮关闭关闭:
$('。close')click(function(e){
e.preventDefault();
var panelId = $(this).closest(li)。remove()。attr(aria-controls);
$(#tab+ panelId).remove();
$ #nav-tabs)。children(li)。last()。addClass(active);
if(counter< = 1){
counter = 1;
} else if(counter> 1){
counter--;
}
return false;
})
看起来不像是使用标准的Bootstrap nav / nav-tabs标记。如果我是您,我会简化添加新标签页和标签内容
有一个功能创建新标签页,选项卡内容,然后使其处于活动状态。您可以使用标签('show')
方法激活新创建的标签:
$('#btnAdd')。click(function(e){
var nextTab = $('#tabs li')。size()+ 1;
// create the tab
$('< li>< a href =#tab'+ nextTab +'data-toggle =tab> Tab'+ nextTab +'< / a& /li>').appendTo('#tabs');
//创建标签内容
$('< div class =tab-paneid =tab' + nextTab +'> tab'+ nextTab +'content< / div>')appendTo('。tab-content');
//使新标签页处于活动状态
$ '#tabs a:last')。tab('show');
});

然后您只需要为您的图片自定义一下。
I am new to Bootstrap, and can't seem to figure this out, i have navbar being used as javascript tab functionality of Bootstrap, which can have dynamically added and removeable nav-links, i have used images rather than default nav-links, my question is when i add the dynamic nav-link, it should become the active class and show its relevant content, at the moment i have to click to make it active, and if i remove any nav-link, the content remains same, is there a way to achieve this function
The html is:
<ul id="nav-tabs" data-tabs="tabs" >
<li class="test" ><img src="assets/img/button_home_selected3.png" class="hover" width="83" /><span>Home</span></a> </li>
</ul>
The tabs are added when this button is clicked:
<a href="#" class="plus" title="Click to add Tabs" ><img src="assets/img/icon_plus.png"/></a>
The li are added using
var counter = 1;
$('.plus').click(function(e) {
e.preventDefault();
var li_count = $('#nav-tabs').find("li.test").length;
if (li_count <= 3)
if(counter <= 3){
$('#nav-tabs').append('<li class="test" ><img src="assets/img/button_home_selected3.png" class="hover" width="83" /><span>Home</span></a><button type="button" class="close">×</button></div></a></li>');
} else { alert("Only 3 Tabs Allowed!")};
The content of tabs are added similarly later;
The active class in tabs is toggled using
$("#nav-tabs").on("click", "a", function(e) {
e.preventDefault();
$(this).tab('show');
$('li.test').each(function() {
if($(this).hasClass('active'))
{
//Active class is applied
$(this).children().children().closest("img").attr("src", "assets/img/button_home_selected3.png");
$(this).find("button").show();
}
else
{
$(this).children().children().closest("img").attr("src", "assets/img/button_home_plain2.png");
$(this).find("button").hide();
}
});
The li are closed using button close in the new nav-links as:
$('.close').click(function(e) {
e.preventDefault();
var panelId = $(this).closest("li").remove().attr("aria-controls");
$("#tab" + panelId).remove();
$("#nav-tabs").children("li").last().addClass("active");
if(counter <= 1){
counter = 1;
}else if (counter > 1) {
counter--;
}
return false;
})
It doesn't look like you're using the standard Bootstrap nav/nav-tabs markup. If I were you I would simplify adding new tabs and tab content like this...
Have a single function that creates the new tab, tab content and then makes it active. You can use the tab('show')
method to activate the newly created tab:
$('#btnAdd').click(function (e) {
var nextTab = $('#tabs li').size()+1;
// create the tab
$('<li><a href="#tab'+nextTab+'" data-toggle="tab">Tab '+nextTab+'</a></li>').appendTo('#tabs');
// create the tab content
$('<div class="tab-pane" id="tab'+nextTab+'">tab' +nextTab+' content</div>').appendTo('.tab-content');
// make the new tab active
$('#tabs a:last').tab('show');
});

Then you just need to customize it a little for your images.
