我正在尝试以这种方式从 XML 中提取文本:
[文本] [文本中的选择] [文本继续] [另一个文本] [另一个选择] [另一个文本继续]
我已经设法部分地做到了这一点,所以它提取了第一段和第一段的选择,但它没有提取第二段的选择,不知道为什么。(在示例中,第一段和第二段的选择相同)。
此外,我正在使用 AJAX 将所选选项的索引发布到 php 和 mysql,但我不知道如何将选项分开。(如:第一选择-->1;第二选择-->3;等等)
我的代码是:
function parseXml(xml)
{
var myArray = [];
var i = 0;
//Megkeressük az összes paragrafust
$(xml).find("Paragraph").each(function()
{
$(this).find("text").each(function(){
{
$("#wrapper").append('<div id="text">' + $(this).text()) + '</div><br />';
$("#text").append('<div id="choice"></div>');
}
});
});
//Each paragraph
$(xml).find("Paragraph").each(function()
{ //Megkeressük az összes választékot
$(this).find("choice").each(function()
{
myArray.push($(this).text());
});
});
$("#choice").append(' ' + myArray[i] + ' ');
sendValue(i);
$("#choice").click(function() {
if(i + 1 >= myArray.length)
{
i=0;
$("#choice").html(' ' + myArray[i] + ' ');
sendValue(i);
}
else
{ i++;
$("#choice").html(' ' + myArray[i] + ' ');
sendValue(i);
}
});
function sendValue(str){
// post(file, data, callback, type); (only "file" is required)
$.post(
"ajax.php", //Ajax file
{ sendValue: str }, // create an object will all values
//function that is called when server returns a value.
function(data){
$('#i').text(data.returnValue);
},
//How you want the data formated when it is returned from the server.
"json"
);
}
}
PHP:
<?php
//Get Post Variables. The name is the same as
//what was in the object that was sent in the jQuery
if (isset($_POST['sendValue'])){
$value = $_POST['sendValue'];
}else{
$value = "";
}
//Because we want to use json, we have to place things in an array and encode it for json.
//This will give us a nice javascript object on the front side.
echo json_encode(array("returnValue"=>"This is returned from PHP : ".$value));
?>
XML:
<?xml version="1.0" encoding="utf-8" ?>
