使用javaScript将String输出到HTML

Question

there have been many questions like this before, but the answer usually involved referencing the element to be outputted to within the script. in my case, elements are created dynamically on load (it's hosted on Tumblr, to be specific), so there's no referable ID for each of the elements I need to output a string to.

is it possible to do this? jQuery can be used if it makes things much simpler. my function takes a string as an input and outputs a string using return .

Answer 1

$('.post .posttext a').html(YourfunctionThatReturnsAString());

这应该做到这一点

Answer 2

$('.post .posttext a') -> this returns an array of a elements.

$('.post').eq(the post number).find('.posttext a') -> replace "the post number" with the number of your post if you want to target something more specific.

You can then call the text("your text") method to set the text.
