javascript js获取title 使用jquery获取所有Form元素值?




js获取title (7)

这是HTML代码:

    $(function(){

    });
    function changeInnerHTML(id)
    {
        if($('#dialog_box_'+id).length)
        {
            var tmp=id.split('_');
             $.get('getDataValues.php?ref='+tmp[0],function(data,status){
                $('#dialog_box_'+id).html(data);
            });
        }
    }
    </script>
    </head>
    <body>
    <div id='container'>


        <h1 id="form-name" style="background-color: rgb(255, 255, 255); box-shadow: none; border: none; margin: 8px 15px;">New Form</h1>

<script type='text/javascript' src='js/form.min.js'></script>
</body>
</html>

这里代码将获取所有表单字段值:

 $("#hidAll").append($("#preview_form :input").map(function () {
     if ($(this).val() != 'Submit') {
         if ($(this).is('select')) {
             var aa = $(this).children('option').map(function () {
                 return $(this).val();
             }).get().join("|");
             return $(this).attr('name') + '|' + aa;
         } else if ($(this).is('input:checkbox')) {
             return $(this).attr('name').substring(0, $(this).attr('name').length - 2) + '|' + $(this).val();
         } else {
             return $(this).attr('name') + '|' + $(this).val();
         }
     }
 }).get().join(","));
 alert($("#hidAll").html());

从这里我得到如下输出值:

textfield_1|dgdfg,
checkboxgroup_1|Option 1,
checkboxgroup_1|Option 2,
checkboxgroup_1|Option 3,
radiobutton_1|Option 1,
radiobutton_1|Option 2,
radiobutton_1|Option 3,
dropdown_1|Option 1!Option 2!Option 3

我希望如下:

 textfield_1|dgdfg,
    checkboxgroup_1|Option 1!Option 2!Option 3,
    radiobutton_1|Option 1!Option 2!Option 3,
    dropdown_1|Option 1!Option 2!Option 3

将其添加到它的末尾:

var array = $("#hidAll").html();

x = array.split(',');
key=s="";
for (i=0; i<x.length; i++) {
  oldkey = key;
  key = x[i].split('|')[0];
  if (oldkey==key) s+='!';
  else s+=',\n'+key+'|';
  s+=x[i].split('|')[1];
}
s = s.substring(1);
$('#hidAll').html(a);

我知道你正在使用jQuery,但对于那些想要纯Javascript解决方案的人:

// Serialize form fields as URI argument/HTTP POST data
function serializeForm(form) {
    var kvpairs = [];
    for ( var i = 0; i < form.elements.length; i++ ) {
        var e = form.elements[i];
        if(!e.name || !e.value) continue; // Shortcut, may not be suitable for values = 0 (considered as false)
        switch (e.type) {
            case 'text':
            case 'textarea':
            case 'password':
            case 'hidden':
                kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            case 'radio':
            case 'checkbox':
                if (e.checked) kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            /*  To be implemented if needed:
            case 'select-one':
                ... document.forms[x].elements[y].options[0].selected ...
                break;
            case 'select-multiple':
                for (z = 0; z < document.forms[x].elements[y].options.length; z++) {
                    ... document.forms[x].elements[y].options[z].selected ...
                } */
                break;
        }
    }
    return kvpairs.join("&");
}


如果你想从简单数组中获取表单中的所有值,你可能会做这样的事情。

function getValues(form) {
    var listvalues = new Array();
    var datastring = $("#" + form).serializeArray();
    var data = "{";
    for (var x = 0; x < datastring.length; x++) {
        if (data == "{") {
            data += "\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
        else {
            data += ",\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
    }
    data += "}";
    data = JSON.parse(data);
    listvalues.push(data);
    return listvalues;
};

如果要使用$(formName).serializeArray()或$(formName).serialize(),则必须在input元素上添加name='inputName' 。 或者不会工作!


尝试将表单输入文本值转换为JavaScript对象...

var fieldPair = {};
$("#form :input").each(function() {
    if($(this).attr("name").length > 0) {
        fieldPair[$(this).attr("name")] = $(this).val();
    }
});

console.log(fieldPair);

您可以使用JQuery的serialize()函数:

    var datastring = $("#preview_form").serialize();
        $.ajax({
            type: "POST",
            url: "your url.php",
            data: datastring,
            success: function(data) {
                 alert('Data send');
            }
        });

并阅读PHP:

echo $_POST['datastring']['dialog_box_textarea_1'];
echo $_POST['datastring']['radiobutton_1'];
........

获取***数据 - ****标记HTML5您可以看到此示例:

<div id="texto" data-author="Ricardo Miranda" data-date="2012-06-21">
<h4>Lorem ipsum</h4>
  <p>
    Lorem ipsum dolor sit amet, ius integre eligendi et,
    sea ut expetendis conclusionemque,
    mel at ornatus invenire. His ad moderatius definiebas omittantur,
    liber saepe albucius sea cu.
    Audire tamquam dolores vis ne, mediocrem consulatu eum ex.
    Duo te agam saepe convenire, et fugit iisque his.
 </p>

<script type="text/javascript">
$(function() {
    alert("The text is write " + $('#texto').data('author'));
});

<div id="texto" data-author='{"nombre":"Ricardo","apellido":"Miranda"}' data-date="2012-06-21">
   ...
</div>

<script type="text/javascript">
$(function() {
    alert("The text is write " + $('#texto').data('author').apellido + ", " +
        ('#texto').data('author').nombre);
});
</script>
