Get source of each image in div with jQuery
提问by streetlight
I'm trying to do a seemingly simple loop, but I keep running into issues.
我正在尝试做一个看似简单的循环，但我一直遇到问题。
I'm trying to loop through a specific div (targeted by an ID), and return the source of the two images inside of it. Here is my HTML:
我正在尝试遍历特定的 div（以 ID 为目标），并返回其中两个图像的源。这是我的 HTML：
<div id="container">
<div class="row selected" id="one"><img src="onei.png"><img src="twoi.png"></div>
<div class="row" id="two"><img src="onei1.png"><img src="twoi2.png"></div>
</div>
And here is my loop:
这是我的循环：
function loop() {
alert()
$('#container row.selected img').each(function() {
alert($(this).attr('src'))
});
}
I can't seem to find out why this isn't working. Shouldn't this loop through each image in my targeted div and alert the source?
我似乎无法找出为什么这不起作用。这不应该循环遍历我的目标 div 中的每个图像并提醒源吗？

maybe something like
也许像
function loop() {
alert()
$('#container .row.selected img').each(function() {
alert($(this).attr('src'))
});
}
you forgot the .on row
你忘了.上row

Maybe you missed the point:
也许你错过了重点：
'#container .row.selected img'
