Jquery - 替换Val（）中的文本

Question

I'm trying to replace parts of a Val() in jquery with some text but am not sure how to do this. $(this).val() returns "# number of...." - I would like to replace # with custom text, but Val doesn't seem to have a replace() function. I'm quite new to JQuery, so I might be missing something obvious. Thanks for any help

Answer 1

You can pass a function to .val() in 1.4+ like this:

$("#mySelector").val(function(i, v) { //index, current value
  return v.replace("#","Custom Text");
});

Answer 2

不要忘记在末尾添加.val（）：

$("#mySelector").val(function(i, v) {return v.replace("#","Custom Text");}).val();
