输入字段不会获得更新的值

Question

I have an input field with id Email and im getting the value of this field to update my object. However when i try to edit it again without a refresh and try to send it via Ajax, email field becomes empty. I get this field by using $("#Email").val() and I tried using .attr("value") as well however this gets the old value of the field not the new value.

My problem is similar to this " jQuery showing empty string on input text? " however, I can't use the solution there as I have to use the input box multiple times after updating.

Answer 1

However when i try to edit it again without a refresh and try to send it via Ajax, email field becomes empty.

Are you sure the page is not refreshing? The field can only become empty from either a refresh, or actual JavaScript code you have written/included that is causing the problem.

$("#Email").val() will read the value and will not blank it out.

.attr("value") will read what the value was when the page loaded, but not accounting for changes made by the user.

My problem is similar to this " jQuery showing empty string on input text? " however, I can't use the solution there as I have to use the input box multiple times after updating.

Do you understand the reason for that solution? The problem there was that the value was captured to a variable Name too early. The solution was to move the call to val() to later. (after blur took effect, not before)

I hope these are helpful, but there's really not much more I could tell you without seeing your code.

I expect this question to be closed due to lack of details. When you post the new question, please try to fix one problem at a time (either "becomes empty", or "gets old value") and post enough details for a solution. (ie an SSCCE)
