大佬教程收集整理的这篇文章主要介绍了jQuery clone链接选择,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
这真的很好,但现在我需要改变一下:克隆最后一组选择.
即:
+- ArgenTina | San Juan | Rawson Chile | Santiago | Chiñihue
然后,如果我点击“”,它将克隆
Chile | Santiago | Chiñihue
而不是第一个.
我最后做的是克隆模板并手动更改值并手动调用“更改”事件,以便在辅助和三元SELECT元素中提供正确的选项.
版本1:http://jsfiddle.net/m4JTQ/2/
版本2(这是一个修改版本摆脱了迭代器:http://jsfiddle.net/Zf7xb/1/
// Version 1 $(function() { // Iterator for the dupe ids var i = 0; $('#clone').click(function() { // put the clone() into cloned var cloned = $('#template').clone(); // Add .dupe class to cloned $(cloned).addClass('dupe'); // Set the id of cloned,use i++ instead of incremenTing it elsewhere. $(cloned).attr('id','duplicate'+ i++); // Append cloned to #filter $(cloned).appendTo('#filter'); // Passing SELEctor rather than iteration chainItWithId($(cloned)); // If this is NOT the first addition,do some kludge if ($('#filter div.dupe').length!==1) { // Set the prevIoUs clone to lastClone var lastClone = $(cloned).siblings('div.dupe:last'); // Set the value of .pais to the value of the prevIoUs .pais $(cloned).find('.pais').val($(lastClonE).find('.pais').val()); // Do the "change" event manually. $(cloned).find('.pais').change(); // Set the value of .provincia to the value of the prevIoUs .provincia $(cloned).find('.provincia').val($(lastClonE).find('.provincia').val()); // Do the "change" event manually $(cloned).find('.provincia').change(); // Set the value of .ciudad to the value of the prevIoUs .cudad $(cloned).find('.ciudad').val($(lastClonE).find('.ciudad').val()); } // Show the hidden div $('#filter div:hidden').show(); }); $('#remove').click(function() { // Remove all but the very last set of options if ($('#filter > div').length > 1) { $('#filter > div').last().remove(); } }); // Manually do the "click" event $('#clone').click(); }); // Here I'm getTing the cloned full SELEctor function chainItWithId(cloned) { // Chain .provincia to .pais in the current clone $(cloned).find('.provincia').chained($(cloned).find('.pais')); // Chain .ciudad to .provincia in the current clone $(cloned).find('.ciudad').chained($(cloned).find('.provincia')); }
在这个版本中没有迭代器,它有点清洁.
// Version 2 $(function() { $('#clone').click(function() { // put the clone() into cloned var cloned = $('#template').clone(); // Add .dupe class to cloned $(cloned).addClass('dupe'); // Set the id to the count of div.dupe elements in #filter // This will increment 0,1,2,3 as you add elements. $(cloned).attr('id','duplicate'+ $('#filter div.dupe').length); // Append cloned to #filter $(cloned).appendTo('#filter'); // Passing SELEctor rather than iteration chainItWithId($(cloned)); // If this is NOT the first addition,do some kludge if ($('#filter div.dupe').length!==1) { // Set the prevIoUs clone to lastClone var lastClone = $(cloned).siblings('div.dupe:last'); // Set the value of .pais to the value of the prevIoUs .pais $(cloned).find('.pais').val($(lastClonE).find('.pais').val()); // Do the "change" event manually. $(cloned).find('.pais').change(); // Set the value of .provincia to the value of the prevIoUs .provincia $(cloned).find('.provincia').val($(lastClonE).find('.provincia').val()); // Do the "change" event manually $(cloned).find('.provincia').change(); // Set the value of .ciudad to the value of the prevIoUs .cudad $(cloned).find('.ciudad').val($(lastClonE).find('.ciudad').val()); } // Show the hidden div $('#filter div:hidden').show(); }); $('#remove').click(function() { // Remove all but the very last set of options if ($('#filter > div').length > 1) { $('#filter > div').last().remove(); } }); // Manually do the "click" event $('#clone').click(); }); // Here I'm getTing the cloned full SELEctor function chainItWithId(cloned) { // Chain .provincia to .pais in the current clone $(cloned).find('.provincia').chained($(cloned).find('.pais')); // Chain .ciudad to .provincia in the current clone $(cloned).find('.ciudad').chained($(cloned).find('.provincia')); }
