我有一系列以下元素:
$('.slidetpl img').each(function () {
if (this.src.length == 0) {
$(this).parent().hide();
}
});
如果图片没有来源,我想隐藏.slidetpl。为此,我尝试了以下方法:
jQuery
但这不起作用。
有人能指出我正确的方向或告诉我我做错了吗?

这对我有效:
// Start an immediate invocable function expression, to auto
// execute the internal code and isolate the code from the
// outside JS scope.
(function( $, window, undefined ){
// Find all the document images and iterate over them. In case you like to
// to iterate only under slidetpl change the selector from
// img to .slidetpl img
$( 'img' ).each(
function() {
// If the empty string is equal with the src attribute of
// of the current item in the iteration
if ( '' === $(this).attr('src') ) {
// Then hide the current item in the iteration.
$(this).hide();
}
}
);
})( jQuery, this )

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="" />
<img src />
<img src="http://www.iconsdb.com/icons/preview/icon-sets/web-2-orange-2/running-man-xxl.png" />

注意,上面的代码将隐藏所有具有空src
属性的图像。如果您只想隐藏.slidetpl
的子元素,则可以将选择器从img
修改为.slidetpl img
。

试试这个:
$(document).ready(function(){
$('.slidetpl img[src=""]').parent().hide();
$('.slidetpl img:not([src=""])').parent().show(); //Can be removed.
});
