在和ajax提交之后,我想要清除表单中除隐藏元素之外的元素: function resetForm(form) {
for (var i = 0; i < form.elements.length; i++) {
// ! do not clean hidden
if (form.elements[i].type !== 'submit' || ...hidden...? ) {
form.elements[i].value = '';
}
}
} 我不知道如何
好的,我有以下分支:
git branch
2012-08-06-AAH
2012-08-06-JWH
2012-08-06-Master
* master
我想去2012-08-06-AAH结账。所以我这样做:
git checkout 2012-08-06-JWH
error: Your local changes to the following files would be overwritten by checkout:
MyProject/canada/rocky_mountaineer/best/coast_to_coast_rail/index.html
我已经运行了git状态和
# On branch master
# Your branch is ahead of 'origin/master' by 4 commits.
# (use "git push" to publish your local commits)
#

# (use "git add <file>..." to update what will be committed)

我有一个isbn搜索input和提交button。在表单提交时,结果显示在表单下方的div中,工作正常。
我的问题是,我能够反复按提交和多个div出现一个接一个。
如何在每次按下提交时替换div的内容?
到目前为止我的代码;
$( "#form" ).submit(function() {
var isbn = $('#isbn_search').val();
var url='https://www.googleapis.com/books/v1/volumes?q=isbn:'+isbn;
event.preven
当表单提交时,我试图通过javascript向dom/ html /site(我是html和js新手)添加一个段落。到目前为止,这就是我所拥有的:
document.addEventListener('DOMContentLoaded',function()
{
var form = document.getElementById("form");
form.addEventListener("submit", add, false);
});
function add(e)
{
var para = document.
class AddTitleToPosts < ActiveRecord::Migration
def self.up
add_column :posts, :title, :string
Post.find(:all).each do |post|
post.update(:title => post.name.upcase)
end
end
def self.down
end
end
就像你不能做什么特别复杂的事情,只是试图通过改变数据库中已经存在的name列的大小写来添加新的列标题。但是我收到了调用私有方法错误的尝试。我猜这跟“自我”有关
