我已经收到帮助这里和stackoverflow使邀请功能。在基于AJAX的搜索框中,可以邀请团队。当搜索一个球队,找到它,然后选择它-球队将被存储在一个数组中。但是,我需要PHP中数组中的数据。
我的问题:我可以使用AJAX将javascript数组转移到PHP吗?代码可以在下面看到。AJAX部分使用jQuery。
//AJAX based search
var $j = jQuery.noConflict();
$j(document).ready(function(){
$j("#search_results").slideUp();
$j("#button_find").click(function(event){
event.preventDefault();
search_ajax_way();
});
$j("#search_query").keyup(function(event){
event.preventDefault();
search_ajax_way();
});
});
function search_ajax_way(){
$j("#search_results").show();
var search_this=$j("#search_query").val();
$j.post("search_team.php", {searchit : search_this}, function(data){
$j("#display_results").html(data);
})
}
// <----- AJAX search ends ------>
//Add-remove teams
//Functional object for team
var Team = function (id, name) {
this.name = name;
this.id = id;
}
//Array which will contain teams
var TeamList = [];
//Checking if the team is already added
function containsTeam(id) {
for (var i = 0; i < TeamList.length; i++) {
if (TeamList[i].id == id) {
return true;
}
}
return false;
}
// Removed team by onclick-event
function removeTeam(id) {
for (var i = 0; i < TeamList.length; i++) {
if (TeamList[i].id == id) {
TeamList.splice(i, 1);
document.getElementById('teams').removeChild(document.getElementById('ta'+id));
}
}
}
function addTeam(tid) {
// Grab the input value
var teamName = document.getElementById(tid).innerHTML;
var teamID = document.getElementById(tid).id;
// If empty value
if(!teamName || !teamID) {
alert('An error occured.');
} else {
if(containsTeam(teamID) == false) {
TeamList.push(new Team(teamID, teamName));
// Create the teams with the value as innerHTML
var div = document.createElement('div');
div.className = 'team-to-invite';
div.setAttribute('onclick', 'removeTeam('+teamID+')');
div.onclick = function() { removeTeam(teamID) };
div.id = 'ta' + teamID;
div.innerHTML = teamName;
// Append it and attach the event (via onclick)
var teams = document.querySelector('#teams').getElementsByTagName('div');
document.querySelector('#teams').appendChild(div);
}
}
return false;
}
团队存储在TeamList()中。
目前最好的方法是将数组编码为字符串,这是您可以POST到PHP脚本的唯一格式。
JSON编码是目前在互联网上发送此类数据最流行的标准。下面是一些编码数据的示例:{
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"GlossList": {
"GlossEntry": {
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef": {
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
一般来说,您将使用jQuery的JSON编码对数组进行编码,将这些数据发布到PHP脚本中,然后在PHP端对其进行解码。
用jQuery发布一个数组
var dataToSend = {
data: TeamList
};
jQuery.ajax({
type: 'POST',
url: "myPhp.php",
data: JSON.stringify(dataToSend),
dataType: "json",
success: function(data){ alert(data); }
});
PHP解码JSON
<?php
$foo = file_get_contents("php://input");
$decoded = json_decode($foo, true);
var_dump($decoded); //Print out the data
$myArray = $foo => data;
我可以将javascript数组转移到PHP中吗
你只能将字符串从执行javascript的浏览器传输到执行php的服务器。但是有一些公认的字符串格式,例如json,可以转换为数组等。
