Question

I FORMULATED MY SELF VERY BADLY!

我将首先谈谈: 我赞赏你的好回答,如果你能够,我会努力回答这一点:(此时我将更具体地谈一下)。

我想的是:<form>element onsubmit, onclick of a hton or what take the Value of a <input category=“text” Value=“Default Value”>,并插入一 couple<span>elements,我叫“持有人”。这一样本可能更能说明:

<head>
<script type="text/javascript">
$(document).ready(function() 
{
$("input[type=button]").click(function //click the button
{ do_the_magic_thing() //make the value from id="txt_inp" appear in class="placeholder"
}); 
});
</script>
</head>

<body>
<form method="POST" action="" id="theForm"> //could also be get, I don t care
<input type="text" id="txt_inp" value="Default Value" onfocus="if (this.value == Default Value) this.value=  "> //this SHOULD make the Default Value dissapear on focus
<input type="button"> //could also be a submit

<span class="placeholder"></span> //$("#txt_inp").value; goes here
<span class="placeholder"></span> //$("#txt_inp").value; goes here
</body>

现在,这是否真的简单:

var do_the_magic_thing = function() {
$(".placeholder").html = $("#txt_inp").value;
};

我现在要问一下——在丹麦晚了: 我明天将回答你的意见:

OLD POST:

~~I am very new to this jQuery thing, but I do understand the basics and all. Let s simplify and say I have a form which looks like this:~~

<form method="POST" action="">
<input type="text" value="Default value">
<input type="submit" value="Click me">
<input type="hidden"> //hidden is for being able to submit by hitting enter
</form>

我用<代码>$.post进行了尝试,但我不能这样做;我不为我工作。

现在,我要取消提交文件(如果存在的话,仅添加“<代码>return不实;在返还价值的职能中这样做),但这并非关键。

我认为,我喜欢这样作。

$.post("test.php", function(data) { alert("This is the data submitted (and cancelled):" + data); }); //I have also tried without the "test.php", that s not it

你们能够告诉我,我是谁错了?

NOTE

It is not necessary, that the submit is cancelled, but I would like that
Nor is it necessary, that POST is the method used, but once again, this is what I prefer

Answer 1

回答你提出的问题的修订本,是,这确实是简单,尽管你“做魔术”功能的正确分类是:

var do_the_magic_thing = function() {
    $( .placeholder ).html($( #txt_inp ).val());
};

P.S. Don t wor对不表示惊讶太大,你的英语比我的丹麦好得多。

将贵表格的复制件改为“制作”,或您案文对“投影”的任何内容和名称,并尝试类似的东西......

$(document).ready(function() {
    $( #myform ).submit(submitMyForm);
})

function submitMyForm(e) {
    var data = new Object();
    data.whatever = $( #myinput ).val();

    var post = new Object();
    //here I use a jquery json extension...you can use anything you like
    post.data = $.toJSON(data);

    $.post("test.php", post, function(returnval) {
        alert(returnval);
    }, "text");

    //this is to stop the normal form submit action
    return false;
}

然后,在你考验中。网址:www.un.org

我认为,你们想要做的是:

<fieldset id="myData">
    <legend>My Data</legend>
</fieldset>

<form id="myForm" method="POST" action="">
    <input type="text" value="Default value">
    <input type="submit" value="Click me">
    <input type="hidden"> //hidden is for being able to submit by hitting enter
</form>

$(function() {
   $( #myForm ).submit(function() {
      //do whatever you want here.
      //this will take place after the form is submitted, but before your ajax request
      $( input[type=text] ).each(function() {
          $( #myData ).append( <div class="placeholder">  + $(this).val() +  </div> );
      });

      //serialize your form data
      var toSubmit = $( input[type=text] ).serialize();

      //do ajax here
      $.post( test.php , toSubmit, function(data) {
        alert( Your AJAX POST request returned:   + data);
      },  text );

      //this will prevent the form from submitting normally
      return false;
   });
});

另见我对你问题的评论。

Answer 4

提交表格时,请在表格中添加以下内容,以取消提交违约事件的提交。

<form onsubmit="return functioncall();">

然后,当你放弃职务时,就会取消违约的形式行动。

EDIT:如果你想看到将要提交的所有数据,你可以采用jquery serialize(>”方法或serializeArray(<>)。

Answer 5

If you re trying to accomplish validation, there s a much easier way, just use a validation plugin like this one: http://docs.jquery.com/Plugins/Validation

使其更容易,并带头制定自己的法典。 Jquery使开发强有力的javascript 申请变得容易......但有时,使用已经写成和被打脚的 st子(至少大部分是这样)。
