我已经构建了一个小的bootstrap 3缩略图文本和img操作，现在我有一个关于如何在页面加载时使其处于活动状态的问题，具体而言我希望#anime1在页面加载时处于活动状态。
查看此manipulation示例。您会看到我只有一些缩略图显示在那里，但是当您与操作交互时，它将显示您需要查看所选navbar标题的所有内容。
那么如何在页面加载时激活它呢？
$(function(){
$('#anime1').click(function(){
$('.column').each(function(){
$( this ).hide( 500 );
});
$('.columns').each(function(){
$( this ).show( 500 );
$('#col1 img').attr('src', 'img/lazy1.png').prepend('background-image', 'url(img/lazy.png)');
$('#col1 h3').text('Grouting!');
$('#col1 p:first').text('Grouting retention text will be displayed here!');
$('#col2 img').attr('src', 'img/lazy1.png').prepend('background-image', 'url(img/lazy.png)');

将触发器附加到处理程序选择器
$('#anime1').click(function(){
//... all the code you have
});
修订：
$('#anime1').click(function(){
//... all the code you have
}).trigger('click');
编辑：修改每条评论的代码。审核代码
请注意，其中一些是偏好，有些可能是矫枉过正，我会在每次更改时提出我的理由：
基于您的列标记示例：注意此处没有ID。
<div class="columns col-xs-2 col-sm-2 col-md-2 col-lg-2">

链接，增加了几件事：一个班级到＆＃39; a＆＃39;标记和data-thing='，每个都有一个名称。我们将使用此thing按名称定位JavaScript对象数组（查找它们）。
<ul class="nav nav-pills">
<li role="presentation"><a id="anime1" class="mylinks" data-thing="grout" href="#">Grouting</a></li>
<li role="presentation"><a id="anime2" class="mylinks" data-thing="ground" href="#">Ground Improvements</a></li>
<li role="presentation"><a id="anime3" class="mylinks" data-thing="earth" href="#">Earth Retention</a></li>
<li role="presentation"><a id="anime4" class="mylinks" data-thing="struct" href="#">Structural Support</a></li>
<li role="presentation"><a id="anime5" class="mylinks" data-thing="tech" href="#">Additional Technologies</a></li>
</ul>
注意这些也可以从物体中注入。
这是对象。我用＆＃34; myApp＆＃34;来命名它。在这个对象中，您可以看到数据以及我使用的一些函数。请参阅整个内嵌评论。
// create my namespace, use any preexisting namespace by that name.
var myApp = myApp || {};
将数据添加到我们的命名空间
// This is the actual data object, it has some defaults that I use
myApp.loadObject = {
defaultActiveLink: "grout",
animateHideDelay: 500,
animateShowDelay: 500,
defaultColumnCount: 8,
// array of "things" that we process (by name)
things: [{

};
在命名空间中添加一些通用函数：
// some generic functions to process my "object" not all these are used so you could clip it down a bit
myApp.arrayObj = {
indexOf: function(myArray, searchTerm, property) {
for (var i = 0; i < myArray.length; i++) {
if (myArray[i][property] === searchTerm) return i;
}
return -1;
},
indexAllOf: function(myArray, searchTerm, property) {
var ai = [];
for (var i = 0; i < myArray.length; i++) {
if (myArray[i][property] === searchTerm) ai.push(i);
}
return ai;
},
lookup: function(myArray, searchTerm, property, firstOnly) {
var found = [];
var i = myArray.length;
while (i--) {
if (myArray[i][property] === searchTerm) {
found.push(myArray[i]);
if (firstOnly) break; //if only the first
}
}
return found;
},
lookupAll: function(myArray, searchTerm, property) {
return this.lookup(myArray, searchTerm, property, false);
},
remove: function(myArray, searchTerm, property, firstOnly) {
for (var i = myArray.length - 1; i >= 0; i--) {
if (myArray[i][property] === searchTerm) {
myArray.splice(i, 1);
if (firstOnly) break; //if only the first term has to be removed
}
}
}
};
向我们的命名空间添加一些自定义函数（只有一个......）
// custom functions
myApp.func = {
/* activate the default specified by name */
setDefault: function() {
var activeDefault = myApp.loadObject.defaultActiveLink;
var defaultIndex = myApp.arrayObj.indexOf(myApp.loadObject.things, activeDefault, "name");
defaultIndex = !!activeDefault ? defaultIndex : 0;
$('.nav-pills').find('.mylinks').eq(defaultIndex).trigger('click');
}
};
标准jQuery的东西，这可能是我们称之为的自定义函数。 这基本上可以解决您的所有代码所做的事情：
// process on click, injecting the appropriate text
$('.nav-pills').on('click', '.mylinks', function() {
// hide using the default hide delay in the object
$('.columns').hide(myApp.loadObject.animateHideDelay);
var thingtype = $(this).data('thing');// added to the link
var thing = myApp.arrayObj.lookup(myApp.loadObject.things, thingtype, "name", true);//lookup by name
var columns = $('.columns');// all the columns
// process the links,showing them
$.each(thing[0].columnData, function(index, item) {
// cache to not do multiple DOM searches
var tn = columns.eq(index).find('.thumbnail');
var cap = tn.find('.caption');
tn.find('img.img-thumbnail').attr('src', item.src).attr('alt', item.alt).prepend('background-image', item.background);
cap.find('h3.thumbnail-head').text(item.headtext);
cap.find('p.thumbnail-desc').text(item.paragraphtext);
// show this one
$('.columns').eq(index).show(myApp.loadObject.animateShowDelay);
});
});
$(function() {
// activate the default specified by name
myApp.func.setDefault();
});

移动在全局范围内单击#anime1时调用的匿名函数，并为其指定名称。然后在准备好文件时调用它。
