我正在使用jQuery过滤div的显示,当我单击一种颜色的名称时,我希望它仅显示与该颜色相对应的div,对于“红色”示例,它可以正常工作,但不是蓝色和绿色,首先我想知道正在发生的问题,然后是修复它的最佳方法。
非常感谢您。

$(document).ready(function(){

因为您有重复的ID(请参阅 id =“ red” ),所以我建议将您的ID转换为类。此外,我建议使用简化的事件处理程序,因为锚文本和您的类名称相似:
$('#colors_buttons a').on('click', function(e) {
// get the button text (ALL, Red, Blue, Green), remove spaces and transform in lower case
var currColor = this.textContent.trim().toLocaleLowerCase();
// now in currColor variable we have a string like red or blue or green
// but this string corresponds to the class name of the divs....
if (currColor == 'all') {
$("#colors div").fadeIn(500);
} else {
// fade out all #colors divs not having such a class
$('#colors :not(.' + currColor + '').fadeOut(200);
// fade in the only one...
$("#colors ." + currColor).fadeIn(500);
}
})
