如上所述，require属性对我不起作用，我已经搜索了一下但是我在这里和网上其他地方找到的答案无法帮助我，如果有人可以帮助我会很棒
应用程序没什么特别的，对我来说只需要学习php和jquery，这里是：
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Sig Generator</title>
<script type="text/javascript" src ="jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="sig.js"></script>
</head>
<body>
<div id="legalform" align ="center">
Rechtsform auswählen:<br><br>
<select id="selection" size="1">
</select><br><br>
<input id="sendLegalForm" type="button" value ="Weiter"/>
</div>
<div id="fields" align="center">
<form id="fieldsForm" >
<br>
<br>
<input id="sendFields" type="submit" value="Weiter"/>
</form>
<br>
</div>
<div id="display" >
<textarea id="textarea" cols="30" rows="20"></textarea>
</div>
</body>
</html>
jquery
$(document).ready(function() {
var $selection ="";
$.ajax({
type:'GET',
url:'http://localhost/php/sig.php?legalforms=true',
dataType:'json',
success: function (data){
$("#display").hide();
var selection = [];
for(var i = 0; i<data.length; i++){
selection.push('<option>', data[i],'</option>');
}
$("#selection").html(selection.join(''));
$("#fields").hide();
},
error: function(jqXHR,textStatus,errorThrown){
console.log(jqXHR);
console.log(textStatus);
console.log(errorThrown);
}
});
$("#sendLegalForm").click(function () {
selection = $('#selection').val();
$.ajax({
type:'GET',
url:'http://localhost/php/sig.php?selectedLegalform='+ selection,
dataType:'json',
success: function (data){
$("#legalform").hide();
$("#fields").show();
var fieldnames =[];
for(property in data.namesToSubmit){
fieldnames.push(property);
}
var fields=[];
for(var i=0; i<data.textfieldHeaders.length; i++){
fields.push(data.textfieldHeaders[i],'<br>','<input name="',fieldnames[i],'" type="text"',data.namesToSubmit[fieldnames[i]] == "required"?"required":"",'>','<br/>');
}
fields.push("<br>", 'Pflichtfelder (*)');
$("#fieldsForm").prepend(fields.join(''));
},
error: function(jqXHR,textStatus,errorThrown){
console.log(jqXHR);
console.log(textStatus);
console.log(errorThrown);
}
});
});
$("#sendFields").click(function(){
$.ajax({
type:'POST',
url: 'http://localhost/php/sig.php?fieldsend='+selection,
data: $("#fieldsForm").serialize(),
success: function (data){
$('#fields').hide();
$('#display').show();
$("#textarea").html(data);
},
error: function(jqXHR,textStatus,errorThrown){
alert('Bitte alle Pflichtfelder ausfüllen.');
console.log(jqXHR);
console.log(textStatus);
console.log(errorThrown);
}
});
return false;
});
});
和php文件
