Question

所以我在javascript中有一个更新函数，它从文件中获取json变量。我在其他函数中使用变量，我不得不为该函数调用相同的文件。我想将这些变量设置为全局，因此我不必在另一个函数中调用该文件，这是更新函数：

    function XML() {
    $.ajax({
        type: "GET",
        url: "xmlconnect.php",
        dataType: "json",   
        success: function(data) {
        for (var i in data) {
            var data = data[i]; 
            var level = data[4];
            var cash = data[6];
            var income = data[7];
            var upkeep = data[42];
            var total_income = income - upkeep;
            var eincome = data[46];
            var health = data[10];
            var max_health = data[11];
            var energy = data[12];
            var max_energy = data[13];
            var stamina = data[14];
            var max_stamina = data[15]; 
            var Exp = data[8];
            var max_exp = data[9];
            var attack = data[16];
            var defense = data[17];
            var skill_points = data[24];
            var health_width = health / max_health * 100;
            var energy_width = energy / max_energy * 100;
            var stamina_width = stamina / max_stamina * 100;
            var exp_width = Exp / max_exp * 100;    
            var sess_id = data['sess']; 
            if(cash < 1000) {
            var user_cash = number_format(cash);
            }
            else {
            var user_cash = format(cash);
            }
    $('#Cash').html('$'+format(user_cash));     
    $('#Income').html('$'+number_format(total_income));
    $('#EIncome').html(number_format(eincome));
    $('#LevelText').html(level);
    $('#HealthText').html(format(health)+'/'+format(max_health));   
    $('#EnergyText').html(format(energy)+'/'+format(max_energy));   
    $('#StaminaText').html(format(stamina)+'/'+format(max_stamina));
    $('#ExpText').html(number_format(exp_width)+'%');       
    $('#HealthWidth').css('width',''+health_width+'%'); 
    $('#EnergyWidth').css('width',''+energy_width+'%'); 
    $('#StaminaWidth').css('width',''+stamina_width+'%');
    $('#ExpWidth').css('width',''+exp_width+'%');   
    $('#Update').load('activity.php');
    }
   }
});
}

例如，我需要在另一个名为“Increase”的函数中使用其中的一些变量而且我设置如下：

    function Increase(Att) {
    $.ajax({
        type: "GET",
        url: "xmlconnect.php",
        dataType: "json",   
        success: function(data) {
        for (var i in data) {
            var data = data[i]; 
            var max_health = data[11];
            var max_energy = data[13];
            var max_stamina = data[15]; 
            var attack = data[16];
            var defense = data[17];
            var skill_points = data[24];    
    $('#AttResults').load('increase.php?att='+Att);     
    $('#Skills').html(number_format(skill_points));
    $('#Att_attack').html(number_format(attack));
    $('#Att_defense').html(number_format(defense));
    $('#Att_max_health').html(number_format(max_health));
    $('#Att_max_energy').html(number_format(max_energy));
    $('#Att_max_stamina').html(number_format(max_stamina)); 
    XML();
    }
   }
});     
}

但我想让第一个XML函数成为全局变量。

根据W3Schools，你可以做到：

variable = value;

（是的，没有＆＃39; var＆＃39;）并且它将使它成为一个全局变量，除非在另一个范围内使用相同的名称。

从JSON变量设置全局变量
