基本上,当客户点击链接时显示的隐藏的div.该div显示一个PHP formail,询问客户有关他/她感兴趣的产品的问题.
<script type="text/javascript"> $(document).ready(function(){ $('.show_hide').showHide({ speed: 500,// speed you want the toggle to happen easing: '',// the animation effect you want. Remove this line if you dont want an effect and if you haven't included jQuery UI changeText: 1,// if you dont want the button text to change,set this to 0 showText: 'REQUEST A QUOTE',// the button text to show when a div is closed hideText: 'CLOSE' // the button text to show when a div is open }); }); </script>
css很简单:
#slidingDiv,#slidingDiv_2{ height:300px; background-color: #e2e2e2; padding:20px; margin-top:10px; border-bottom:30px solid #000000; display:none; }
这是外部java脚本:
(function ($) { $.fn.showHide = function (options) { //default vars for the plugin var defaults = { speed: 1000,easing: '',changeText: 0,showText: 'Show',hideText: 'Hide' }; var options = $.extend(defaults,options); $(this).click(function () { $('.toggleDiv').slideUp(options.speed,options.easing); // this var stores which button you've clicked var toggleClick = $(this); // this reads the rel attribute of the button to determine which div id to toggle var toggleDiv = $(this).attr('rel'); // here we toggle show/hide the correct div at the right speed and using which easing effect $(toggleDiv).slideToggle(options.speed,options.easing,function() { // this only fires once the animation is completed if(options.changeText==1){ $(toggleDiv).is(":visible") ? toggleClick.text(options.hideText) : toggleClick.text(options.showText); } }); return false; }); }; })(jQuery);
现在我相信在这段代码中,即使没有显示,表单也会自动加载.我可能错了,请纠正我,如果是这样.
问题,如何确保div中的iframe只有当div不再隐藏时才会加载?
解决方法
而不是使用其src属性加载iframe,而是使用data-src属性加载它.为了它的价值,提供您父母div可见时使用的最终位置.
<div class="hidden_element"> <iframe src="http://msdn.microsoft.com"></iframe> </div>
当您显示父div时,发出一个使用iframe属性data-src的回调,并将其值设置为iframe的src属性,使其加载.
// Show our element,then call our callback $(".hidden_element").show(function(){ // Find the iframes within our newly-visible element $(this).find("iframe").prop("src",function(){ // Set their src attribute to the value of data-src return $(this).data("src"); }); });
