我有一个运行良好的引导程序选项卡。 如果没有将其插入到选项卡中,我的区域地图将运行良好。 我使用了Matt Stow提供的“响应式图像映射jQuery插件”,效果也很好。
症状: 然后,我将区域地图放入其中一个标签中,默认情况下该标签未处于活动状态。 然后,我单击选项卡以使其显示。因此,img很好地显示了出来。 但是区域图不起作用。我看不到可点击的矩形。 但是,如果我手动调整导航器的大小,则该区域图将起作用。
页面:https://boutique.bilp.fr/71-les-pieds-de-poteaux.html 选择选项卡“ Guide de choix”,白色矩形应该是可单击的。直到我手动调整窗口大小才可以。
原因: 负责的是响应式图像映射jQuery插件。在其代码中,它调用jquery .width()方法来获取应在地图上工作的img的宽度。并且由于父项(选项卡)是隐藏的,因此返回的宽度是错误的。并且它使用它来调整地图的大小...值不正确。然后,地图太小了,似乎无法正常工作。
感谢您的帮助。

一种解决方案是通过在调用width()之前使祖先可见来修改“响应式图像映射jQuery插件”。
原始代码:

;(function($) {
$.fn.rwdImageMaps = function() {
var $img = this;
var rwdImageMap = function() {
$img.each(function() {
if (typeof($(this).attr('usemap')) == 'undefined')
return;
var that = this,
$that = $(that);
// Since WebKit doesn't know the height until after the image has loaded, perform everything in an onload copy
$('<img />').on('load', function() {
var attrW = 'width',

$(window).resize(rwdImageMap).trigger('resize');
