用鼠标悬停显示信息

Question

I'm trying to create an application that lets the user place an order from the menu. My problem is When the user hovers the mouse over one of the images in the menu, another image should be displayed with the description and price of the item. The id attribute of each image identifies the image to be displayed when it's rolled over. I tired to manged the first image to flip and show the description and price but the problem is when you click on the first image it does not show the price on the order box and the image is not showing either

 $(function(){ //declare prices and varaibles var item1 = $("#item1"); item1.val(7.99); var item2 = $("#item2"); item2.val(1.99); var item3 = $("#item3"); item3.val(9.99); var item4 = $("#item4"); item4.val(12.99); var item5 = $("#item5"); item5.val(17.99); var item6 = $("#item6"); item6.val(3.99); var Total = $("#Total"); var Amount = 0; //onclick var item = $(".item"); var txtArea = $("#txtArea"); var orderList = ""; //Events item.click(function(event){ Amount+=parseFloat($(event.target).val()); orderList+=parseFloat($(event.target).val())+"$ -"+event.target.id +"\\n"; txtArea.val(orderList); Total.html("Total: "+Amount.toFixed(2)+"$"); }); //Events item.hover(function(){ $(event.target).text($(event.target).val()+"$"); $(event.target).addClass("dark"); }, function(){ $(event.target).text(""); $(event.target).removeClass("dark"); }); //Clear Button var ClearOrder = $("#ClearOrder"); //Events ClearOrder.click(function(){ Amount = 0; Total.html("Total: "+Amount.toFixed(2)); orderList =""; txtArea.val(orderList); }); })

Answer 2

i added rotate card on hover for any item & set item1 as first item

item.mouseleave(function() { $('.flip-card-inner').removeClass('flipcard'); }); $('.flip-card-inner').addClass('flipcard');

added css class .flipcard { transform: rotateY(180deg); } .flipcard { transform: rotateY(180deg); }

also added img & price onhover event using $('.flip-card-back').html($(event.target).val()+'$'); $('.flip-card-back').css('background', $(event.target).css('background')); $('.flip-card-back').html($(event.target).val()+'$'); $('.flip-card-back').css('background', $(event.target).css('background'));

 $(function() { //declare prices and varaibles var item1 = $("#item1"); item1.val(7.99); var item2 = $("#item2"); item2.val(1.99); var item3 = $("#item3"); item3.val(9.99); var item4 = $("#item4"); item4.val(12.99); var item5 = $("#item5"); item5.val(17.99); var item6 = $("#item6"); item6.val(3.99); var Total = $("#Total"); var Amount = 0; //onclick var item = $(".item"); var txtArea = $("#txtArea"); var orderList = ""; //Events item.hover(function(event) { $('.flip-card-back').html($(event.target).val() + '$'); $('.flip-card-back').css('background', $(event.target).css('background')); $('.flip-card-inner').addClass('flipcard'); }, function() { $('.flip-card-inner').removeClass('flipcard'); }); item.click(function(event) { Amount += parseFloat($(event.target).val()); orderList += parseFloat($(event.target).val()) + "$ -" + event.target.id + "\\n"; txtArea.val(orderList); Total.html("Total: " + Amount.toFixed(2) + "$"); }); //Events item.hover(function() { $(event.target).text($(event.target).val() + "$"); $(event.target).addClass("dark"); }, function() { $(event.target).text(""); $(event.target).removeClass("dark"); }); //Clear Button var ClearOrder = $("#ClearOrder"); //Events ClearOrder.click(function() { Amount = 0; Total.html("Total: " + Amount.toFixed(2)); orderList = ""; txtArea.val(orderList); }); })
