在AJAX调用中使用FOR循环 [英] Use a FOR loop within an AJAX call

问题描述

因此，我正在尝试发送AJAX请求，但是正如您所看到的，我的表单中有很多字段，并且我使用数组进行验证，我想使用相同的数组，传递要通过AJAX发送的值:

我从来没有在JS中使用过for循环，但是无论如何看起来还是很熟悉.

制作循环的方式，显然是行不通的:

(i = 0; i< required.length; i ++)的

  {var required [i] = $('#'+ required [i]).attr('value'); 

这将创建我想要的变量，如何使用它们?

希望，你们可以帮助我！！！非常感谢你！

  required = ['nome'，'sobrenome'，'endereco'，'codigopostal'，'localidade'，'telemovel'，'email'，'codigopostal2'，'localidade2'，'endereco2'，'nif'，'entidade'，'codigopostal3'，'localidade3'，'endereco3'，'nserie'，'modelo']；函数ajaxrequest(){for(i = 0; i< required.length; i ++){var required [i] = $('#'+ required [i]).attr('value');var dataString ='nome ='+必填[0] +'& sobrenome ='+必填[1];}$ .ajax({输入:"POST"，网址:"ajaxload/como.php"，数据:dataString，成功:function(){$(.agendarleft").html("SUCESS");}}); 

解决方案

为帮助确保传递适当的元素ID和值，请遍历各种元素并将数据首先添加到对象中.

jQuery:

  required = ['nome'，'sobrenome'，'endereco'，'codigopostal'，'localidade'，'telemovel'，'email'，'codigopostal2'，'localidade2'，'endereco2'，'nif"，"entidade"，"codigopostal3"，"localidade3"，"endereco3"，"nserie"，"modelo"]]；函数ajaxrequest(){var params = {};//初始化对象//循环遍历输入数组for(var i = 0; i< required.length; i ++){//设置对象的键/属性(输入元素)var ele = required [i];//将属性添加到对象并设置值params [ele] = $('#'+ ele).val();}$ .ajax({输入:"POST"，网址:"ajaxload/como.php"，数据:参数，成功:function(){$(.agendarleft").html("SUCESS");}});}

So, what i'm trying to do is to send an AJAX request, but as you can see i have many fields in my form, and i use an array to make validations, i would like to use the same array, to pass the values to be sent via AJAX:

I never used the for loop in JS, but seems familiar anyway.

The way the loop is made, obviously wont work:

for (i=0;i<required.length;i++) {
        var required[i] = $('#'+required[i]).attr('value');

This will create the variables i want, how to use them?

HOPEFULLY, you guys can help me!!! Thank you very much!

required = ['nome','sobrenome','endereco','codigopostal','localidade','telemovel','email','codigopostal2','localidade2','endereco2','nif','entidade','codigopostal3','localidade3','endereco3','nserie','modelo'];              


function ajaxrequest() {
    for (i = 0; i < required.length; i++) {
        var required[i] = $('#' + required[i]).attr('value');
        var dataString = 'nome=' + required[0] + '&sobrenome=' + required[1];
    }
    $.ajax({
        type: "POST",
        url: "ajaxload/como.php",
        data: dataString,
        success: function() {
            $(".agendarleft").html("SUCESS");
        }
    });

解决方案

To help ensure that the appropriate element IDs and values are passed, loop through the various elements and add the data to an object first.

jQuery:

required = ['nome', 'sobrenome', 'endereco', 'codigopostal', 'localidade', 'telemovel', 'email', 'codigopostal2', 'localidade2', 'endereco2', 'nif', 'entidade', 'codigopostal3', 'localidade3', 'endereco3', 'nserie', 'modelo'];

function ajaxrequest() {
    var params = {}; // initialize object

    //loop through input array
    for (var i=0; i < required.length; i++) {             
        // set the key/property (input element) for your object
        var ele = required[i]; 
        // add the property to the object and set the value
        params[ele] = $('#' + ele).val(); 
    }
    $.ajax({
        type: "POST",
        url: "ajaxload/como.php",
        data: params,
        success: function() {
            $(".agendarleft").html("SUCESS");
        }
    });
}
