注意:以下是我网站上该网页的工作示例。目前它仅适用于DayZ部分。 https://www.brotherhoodgaming.net/reddit.php
修改 这是我点击redditHeader
的HTML<div class="redditHeader grey3">
<p class="white floatleft">
DayzUnderground
</p>
<i class="material-icons redditHeaderCollapse">
arrow_drop_down
</i>
</div>
在过去几个月的StackOverflow的帮助下,我构建了我的第一个网站的骨架。我有一个庞大的Jquery JSON函数,它根据subreddit的URL从reddit中提取数据。我还有3个<div>
( Dayz , BuildaPCSales 和 Bronies 作为测试)。
当我点击任何一个栏时,我希望我的Javascript函数动态加载来自'https://www.reddit.com/r/' + encodeURIComponent(subreddit) + '.json'
的数据 - 其中(subreddit)是<div>
的val()文本。在此示例中,如果我单击“Dayz”,我希望reddit从r/dayz.json
加载数据,而无需手动在代码中键入URL。
这是我的javascript函数。它目前可以成功地用于我手动输入URL的任何reddit。
<script>
$('.redditHeader').click(function() {
var subreddit = $(this).children('.redditBanner').text();
loadRedditData(subreddit);
});
function loadRedditData(subreddit) {
$.getJSON('https://www.reddit.com/r/' + encodeURIComponent(subreddit) + '.json').then(function (data) {
console.log(data);
function foo(data) {
$.each(
// iterate over 10 children, starting at the 0th index
data.data.children.forEach(foo); function foo(item, index) { //SAYS I AM MISSING A ")" HERE
//Load reddit title in correct div//
$('#news' + i + ' .redditTitle').append(
$('<a>')
.attr('href', 'https://m.reddit.com/' + post.data.permalink)
.text(post.data.title)
);
//Load reddit Score (net UP - DOWN)//
$('#news' + i + ' .redditScore').prepend(
$('<p>')
.attr('class', 'redditUpvoteScore')
.text(post.data.score)
);
//Load reddit post-text in HTML format//
$('#news' + i + ' .redditPost').append(
$('<p>')
.text(post.data.selftext_html)
);
//Load sub-reddit name in HTML format//
/*$('#news' + i + ' .subRedditName').append(
$('<p>')
.attr('class', 'subRedditFormat')
.text('r/' + post.data.subreddit)
);*/
//Load post thumbnail URL into an <a> tag wrapping the image//
$('#news' + i + ' .redditThumbnail').append(
$('<a>')
.attr('href', post.data.url)
.attr('class', 'thumbURL')
);
//Load actual thumbnail into the <a> wrapper tag with the thumbURL class//
$('#news' + i + ' .thumbURL').append(
$('<img>')
.attr('src', post.data.thumbnail)
.attr('class', "image news hide floatleft")
);
//Load reddit Username and URL into container DIV//
$('#news' + i + ' .userNameContainer').append(
$('<a>')
.attr('class', 'redditUserName')
.attr('href', 'https://m.reddit.com/user/' + post.data.author)
.text(post.data.author)
);
// Convert post creation time to local time//
var utcSeconds = post.data.created_utc;
var d = new Date(0);
// The 0 is the key, which sets the date to the epoch
d.setUTCSeconds(utcSeconds);
//Use Moment.js to calculate relative date and append to DIV//
$('#news' + i + ' .redditDate').append(
moment(d).fromNow()
);
//Decodes HTML into correct format by replacing unescaped characters//
$('.redditPost').each(function(){
var $this = $(this);
var t = $this.text();
$this.html(t.replace('<','<').replace('>', '>'));
$this.html(t.replace('null','').replace('null', ''));
});
//Checks for "self" tagged images and replaces with placeholder image//
function changeSourceAll() {
var images = document.getElementsByTagName('img');
for (var i = 0; i < images.length; i++) {
if (images[i].src.indexOf('self') !== -1) {
images[i].src = images[i].src.replace("self", "css/images/default.jpg");
}
}
for (var i = 0; i < images.length; i++) {
if (images[i].src.indexOf('default') !== -1) {
images[i].src = images[i].src.replace("self", "css/images/default.jpg");
}
}
for (var i = 0; i < images.length; i++) {
if (images[i].src.indexOf('https://www.brotherhoodgaming.net/default') !== -1) {
images[i].src = images[i].src.replace("https://www.brotherhoodgaming.net/default", "css/images/default.jpg");
}
}
}
changeSourceAll();
}
)
}
});
}
这是我用类“redditHeader”从<div>
获取文本值的可怕尝试。
$('.redditHeader').each().on('click', function (){
$('p[class="white"]').val();
})
提前感谢您提供任何可能的帮助。我很难过!
答案 0 :(得分:1)
这样的事情应该有效:
$('.redditHeader').click(function (event){
var subreddit = $(event.currentTarget).find('.white').text();
loadRedditData(subreddit);
})
$(event.currentTarget)获取已单击的元素,find()将获取此元素的子元素。最后,我调用loadRedditData(subreddit)。
我压制了each(),因为我真的不明白你试图用它来实现的目标。

您无法获得.val()
代码的<p>
!使用.text()
!
$('.redditHeader').click(function() {
var subreddit = $(this).children('.white').text();
loadRedditData(subreddit);
});
