javascript jquery html-如何将标题属性分配给.class

Question

I have a div that holds the results that is retrieved by ajax. Depends on the result, the div will be assigned a different css class. I want to attach the title attribute to the classes so that class 1 will show the title 1, and class 2 will show the title 2. My routine is somewhat complicated, so assigning the attr('title','xxx') each time I switch the class has not been successful.

Is it possible to attach the title to a css class like the pseudo code below?

TIA

.class1
{
title: 'class1';

}

.class2
{
title: 'class2';

}

Answer 1

Your explanation is a bit unclear, but you may want to try adding live() to the chain before you call attr(title,xxx) . AJAX requests (asynchronous ones) load data into the DOM after the onReady function executes your script, so whatever selector you are using may be invalid at the time the script executes.

Answer 2

No, it isn't.

CSS is designed to describe the presentation of a DOM, not its content (even though it dips a toe into that area with content ).

Answer 3

您将仅需使用attr(title,xxx)即使您的例程很复杂，也可以使用jquery选择器在第1行或第2行中进行操作
