如何调用php函数来响应sciter窗口的元素

下面的例子我们来看一下如何在sciter的按钮上绑定php函数,本事例位于examples/callback文件夹下

1.编写入口文件

<?php
//创建一个sciter的实例
$oSciter = new PHPSciter();
//设置资源加载路径
$oSciter->setResourcePath('file://' . __DIR__ . '/res/');
//设置sciter的窗口大小
$oSciter->setWindowFrame(100, 100, 100 + 500 + 1, 100 + 500 + 1);
//设置sciter的标题为hello
$oSciter->setWindowTitle('hello');
//设置资源目录下加载的入口文件
$oSciter->loadFile('helloword.php');

//设置PHPSCITER的选项
$oSciter->setOption(PHPSciter::SCITER_SET_SCRIPT_RUNTIME_FEATURES,
PHPSciter::ALLOW_FILE_IO | PHPSciter::ALLOW_SOCKET_IO | PHPSciter::ALLOW_EVAL |
                               PHPSciter::ALLOW_SYSINFO);

//运行dialog窗体
$res = $oSciter->run(PHPSciter::SW_TITLEBAR | PHPSciter::SW_RESIZEABLE | PHPSciter::SW_MAIN | PHPSciter::SW_ENABLE_DEBUG
|PHPSciter::SW_CONTROLS);
?>

2.调用defineFunction在sciter按钮处绑定php函数

编写callback.php，使用defineFunction把我们的php函数加入到sciter执行引擎中，从而使php执行引擎和Sciter执行引擎进行交互，但是要注意defineFunction一定要在调用PHPSciter->run之后使用，因为每次在PHPSciter加载页面完成后，都会清理PHP内核中的CG(function_table)(php在本页面中所有的用户函数)、EG(zend_constants)(php在本次sciter执行过程中所有使用的用户级别常量)、位于EG(symbol_table)中所有的变量进行回收，所以defineFunction必须要在PHPSciter->run之后调用

<?php

class classTest
{
    static public function plus($a)
    {
        return $a + 30;
    }

    static public function sum($a, $b, $c)
    {
        return $a + $b + $c;
    }

    static public function float_($float)
    {
        var_dump(is_float($float), $float);

        return 33.44;
    }

    static public function contact($str_1, $str_2)
    {
        return $str_1 . '-' . $str_2;
    }

    static public function contact_chinese($str_1, $str_2)
    {
        return $str_1 . '-' . $str_2;
    }

    static public function response_chinese()
    {
        return '我是汉字，你好世界';
    }

    static public function null_($null)
    {
        var_dump($null == null);

        return null;
    }

    static public function bool_false($false)
    {
        var_dump($false == false);

        return false;
    }

    static public function bool_true($true)
    {
        var_dump($true == true);

        return true;
    }

    static public function arrmap($array, $str_1, $str_2, $num_1, $num_2)
    {
        // var_dump(is_array($array),$array, $str_1, $str_2, $num_1, $num_2);
        $str = self::contact($str_1, $str_2);
        $num = self::sum($num_1, $num_2, 300);

        return array(
            $str,
            'str'           => $str,
            'num'           => $num,
            'this_is_array' => array(
                'key_1'             => 'this is string a',
                'key_2'             => 100,
                'this_is_array_too' => array(
                    'key_3' => 'this is string b',
                    'key_4' => null,
                ),
            ),
            300,
            400             => 'this is string',
            'key_5'         => null,
        );
    }
}

PHPSciter::defineFunction('plus', 'classTest::plus');
PHPSciter::defineFunction('sum', 'classTest::sum');
PHPSciter::defineFunction('float', 'classTest::float_');
PHPSciter::defineFunction('contact', 'classTest::contact');
PHPSciter::defineFunction('contact_chinese', 'classTest::contact_chinese');
PHPSciter::defineFunction('response_chinese', 'classTest::response_chinese');
PHPSciter::defineFunction('nul', 'classTest::null_');
PHPSciter::defineFunction('bool_true', 'classTest::bool_true');
PHPSciter::defineFunction('bool_false', 'classTest::bool_false');
PHPSciter::defineFunction('arrmap', 'classTest::arrmap');
?>

3.绑定callback中定义的php函数

用html、css和tscript编写sciter的运行界面，并且绑定我们在php中定义的plus、sum、float、contact、contact_chinese、response_chinese、nul、bool_true、bool_false、arrmap 函数

<?php
 include_once "callback.php";
 ?>
<html>
<meta http-equiv=Content-Type content="text/html;charset=utf-8">
<div>
    Request & Get Int:
    <button id="plus_btn">Click Plus</button>
    <button id="sum_btn">Click Sum</button>
    <br/>

    Request & Get Float:
    <button id="float_btn">Click Float</button>
    <br/>

    Request & Get String:
    <button id="contact_btn">Click Contact</button>
    <button id="contact_abc_btn">Click ABC Contact</button>
    <button id="chinese_btn">Click 汉字参数与响应</button>
    <button id="response_chinese_btn">Click 响应汉字</button>
    <br/>

    Request & Get NULL:
    <button id="null_btn">Click Null</button>
    <br/>

    Request & Get Bool:
    <button id="bool_true_btn">Click Bool True</button>
    <button id="bool_false_btn">Click Bool Flase</button>
    <br/>

    Request & Get Array:
    <button id="array_btn">Click Array</button>
    <br/>

    Request & Get Map:
    <button id="map_btn">Cliek Map</button>
    <br/>
</div>
<br /><hr />
<div id="data_json"> </div>
<br /><hr />
<div id="data_area">

</div>
<script type="text/tiscript">
$(#plus_btn).on("click", function() {

    var str = view.contact_chinese("我是汉字","你好世界");
    $(#data_json).html = JSON.stringify(str);
    $(#data_area).html = str;

$(#response_chinese_btn).on("click", function() {
    var str = view.response_chinese();
    $(#data_json).html = JSON.stringify(str);
    $(#data_area).html = str;

$(#null_btn).on("click", function() {
    var nul = view.nul(null);
    var str = "get null faild";
    if (nul == null) {
        str = "get null success";
    }
    $(#data_json).html = "";
    $(#data_area).html = str;

    if (bol == true) {

    }

    $(#data_json).html = JSON.stringify(bol);
    $(#data_area).html = str;
});

$(#bool_false_btn).on("click", function() {
    var bol = view.bool_false(false);
    var str = "get flase faild";
    if (bol == false) {
        str = "get flase success";
    }
    $(#data_json).html = JSON.stringify(bol);
    $(#data_area).html = str;
});

$(#array_btn).on("click", function() {
    var alphas = [1111,2222,3333,4444];

    var arr = view.arrmap(alphas,"test","neeke",100,200);

    var result = "";
    result += "arr.length -> " + arr.length + "<br />";

    var i = 0;
    for(var key in arr) {
        i++;
        result += " i: " + i;
        result += " key -> " + key + " val -> " + JSON.stringify(arr[key]) + "<br />";
    }

    $(#data_json).html = JSON.stringify(arr);
    $(#data_area).html = result;
});

$(#map_btn).on("click", function() {
    //var map_ = {"a","b",110,119};
    var map_ = {"aaaa":123,"bbbb":"cccc","d":"110","e":null};
    var map = view.arrmap(map_,"test","neeke",100,200);

    var result = "";
    result += "map.length -> " + map.length + "<br />";

    var i = 0;
    for(var key in map) {

    //view.msgbox(#information, "map.this_is_array.this_is_array_too.key_3 -> " + map.this_is_array.this_is_array_too.key_3);
});

</html>

4.运行sciter界面

点击不同的按钮，我们就可以执行我们在sciter中注册的php函数了
