Question

我有几个名称相同的复选框，并使用方括号，以获得数组

<label>
          <input type="checkbox" value="Tlocrt objekta" name="dokument[]" > Tlocrt objekta </input>
        </label>
        <label>
        <input type="checkbox" value="Građevinska dozvola" name="dokument[]" > Građevinska dozvola </input>
      </label>
      <label>
        <input type="checkbox" value="Glavni projekt" name="dokument[]" > Glavni projekt </input>
      </label>
      <label>
        <input type="checkbox" value="Izvedbeni projekt" name="dokument[]" > Izvedbeni projekt </input>
      </label>
      <label>
        <input type="checkbox" value="Elaborat legalizacije" name="dokument[]" > Elaborat legalizacije </input>
      </label>
      <label>
        <input type="checkbox" value="Elaborat etažiranja" name="dokument[]" > Elaborat etažiranja </input>
      </label>
      <label>
        <input type="checkbox" value="Projekt preuređenja" name="dokument[]" > Projekt preuređenja </input>
      </label>
      <label>
        <input type="checkbox" value="Završno izvješće nadzornog inženjera" name="dokument[]" > Završno izvješće nadzornog inženjera </input>

我正在尝试从此复选框中获取值

var user_Docs       =    $("input:checkbox[name='dokument[]']:checked");

并使用此

将它们传递给PHP

//data to be sent to server
            post_data = {'name':user_Name, 'email':user_Email, 'telefon':user_Phone, 'objekt':user_Objekt, 'kvadratura':user_Kvadratura, 'god_izgradnje':user_Izgradnja, 'kat_cestica':user_Cestica, 'kat_opcina':user_Opcina, 'namjena':user_Namjena, 'napomena':user_Napomena, 'dokument[]':user_Docs};

这是我的Javascript

$(document).ready(function() {
    $("#submit_btn").click(function() { 
        //get input field values
        var user_Name       = $('input[name=name]').val();

        var user_Napomena    = $('textarea[name=napomena]').val();
        var user_Docs       =    $("input:checkbox[name='dokument[]']:checked");

        //simple validation at client's end
        //we simply change border color to red if empty field using .css()
        var proceed = true;

            proceed = false;
        } */

        //everything looks good! proceed...
        if(proceed) 
        {
            //data to be sent to server
            post_data = {'name':user_Name, 'email':user_Email, 'telefon':user_Phone, 'objekt':user_Objekt, 'kvadratura':user_Kvadratura, 'god_izgradnje':user_Izgradnja, 'kat_cestica':user_Cestica, 'kat_opcina':user_Opcina, 'namjena':user_Namjena, 'napomena':user_Napomena, 'dokument[]':user_Docs};

            //Ajax post data to server
            $.post('contact_me.php', post_data, function(response){  

                //load json data from server and output message     
                if(response.type == 'error')

我的表单正在运行，但我没有从电子邮件中的复选框中获取值。更确切地说，我正在尝试从表单收集数据并发送包含相同数据的电子邮件。所有数据都在电子邮件中，但复选框的值未显示。不知怎的，我没有得到它们。有人能帮帮忙吗？

Answer 1

我认为您正在研究AJAX表单提交。阅读以下示例：Submitting HTML form using Jquery AJAX

或者看起来您的表单无法在任何地方提交操作。要将其传递到$ _POST，您需要让标签说出类似

的内容

那个output.php是$ _POST将被填充的地方。

Answer 2

序列化表单，而不是手动创建要传递的数组。

http://jsfiddle.net/44H7b/

  $("#form").submit(function (event) {
        console.log($(this).serializeArray());
        event.preventDefault();
    });

Answer 3

答案是序列化[link] http://api.jquery.com/serialize/ 这意味着替换这部分代码 //data to be sent to server post_data = {'name':user_Name, 'email':user_Email, 'telefon':user_Phone, 'objekt':user_Objekt, 'kvadratura':user_Kvadratura, 'god_izgradnje':user_Izgradnja, 'kat_cestica':user_Cestica, 'kat_opcina':user_Opcina, 'namjena':user_Namjena, 'napomena':user_Napomena, 'dokument[]':user_Docs};

这一个 post_data = $('form#yourForm').serialize(); 好吧不完全一样。我更改了ID并输入了自己的表单ID

没有从表单复选框获取并将jquery中的值传递给$ _POST
