JQuery - Click Submit Button Get Form Value
提问by user982853
I have the following function and all i am trying to do is get the value out of the form field.
我有以下功能,我要做的就是从表单字段中获取值。
$( ".searchbutton" ).click(function() {
var tc = $(this).closest("form input[name='searchbox']").val();
alert(tc);
return false;
});
The alert keeps telling me "Undefined". I have treid closest, parent, parents, find, etc. I don't know what im doing wrong. Im clicking the submit button and all i want in return is the value in the search box. Please help.
警报一直告诉我“未定义”。我已经 treid 最亲近的,父母,父母,找到等。我不知道我做错了什么。我点击提交按钮,我想要的只是搜索框中的值。请帮忙。

How about just using $('input[name="searchbox"]')
selector:
只使用$('input[name="searchbox"]')
选择器怎么样:
$( ".searchbutton" ).click(function() {
var tc = $('input[name="searchbox"]').val();
alert(tc);
return false;
});
