jQuery悬停并显示完整标题

Question

I currently create a toggle div, when the div not hover the long title will automatically show ... for the rest characters more than 30, So far I have successfully created the ... function .

I need when hover the div the long title will show exactly the long title full text.

JS Fiddle

JS

     $('#popup_survey_whitebox_content').hide();



 $("label#popup_survey_label_title").text(function (index, currentText) {
     var newText = currentText.substr(0, 30);
     if (currentText.length > 30) newText += "...";

     return newText;
 });

 $("#popup_survey_whitebox").hover(function () {
     $('#popup_survey_whitebox_content').stop().animate({
         opacity: 1,
         height: "toggle"
     }, 500, function () {
         // Animation complete.
     }).css('position', 'relative');



     $("#popup_survey_end_whitebox").click(function () {
         $("#popup_survey_whitebox").remove();
     });

 });

For example :

full text long title : testingtestingtestingtestingtesting123

long title : testingtestingtestingtestingtesting...

when hover it show testingtestingtestingtestingtesting123

mouseout: testingtestingtestingtestingtesting... again

You have to cache your text like this:

 $('#popup_survey_whitebox_content').hide();

 var orig = '', // create var to cache the original text
     newText = ''; // create var to cache the new Text with "..."

 $("label#popup_survey_label_title").text(function (index, currentText) {
     orig = currentText;
     newText = currentText.substr(0, 30);

     if (currentText.length > 30) newText += "...";

     return newText;
 });

 $("#popup_survey_whitebox").hover(function () {
     $('#popup_survey_whitebox_content').stop().animate({
         opacity: 1,
         height: "toggle"
     }, 500, function () {
         $("label#popup_survey_label_title").text(orig); // Here put the original text.
     }).css('position', 'relative');

 }, function () {
     $('#popup_survey_whitebox_content').stop().animate({
         opacity: 1,
         height: "toggle"
     }, 500, function () {
         $("label#popup_survey_label_title").text(newText); // Here put the new text with "..."
     }).css('position', 'relative');
 });

 $("#popup_survey_end_whitebox").click(function () {
     $("#popup_survey_whitebox").remove();
 });

The syntax is this:

$(elem).hover(fn, fn);

first fn gets executed when you hover the element and second fn is executed when you mouse out of the element. it is just mouseenter, mouseleave.
