Question

我写了一个Javascript函数

jQuery(document).ready( function newbie($) {

    //var email = 'emailaddress'
    var data = {
        action: 'test_response',
        post_var: email
    };
    // the_ajax_script.ajaxurl is a variable that will contain the url to the ajax processing file
    $.post(the_ajax_script.ajaxurl, data, function(response) {
        alert(response);
    });
    return false;
});

我将使用

打电话

newbie();

但是我想在调用函数时传入一个变量（电子邮件地址），但我不知道该怎么做。那个$符号似乎妨碍了我！任何想法都非常感激。

Answer 1

jQuery(document).ready(function(){
   var email = 'emailaddress';
   newbie(email);
});


function newbie(email) {
    var data = {
        action: 'test_response',
        post_var: email
    };
    // the_ajax_script.ajaxurl is a variable that will contain the url to the ajax processing file
    $.post(the_ajax_script.ajaxurl, data, function(response) {
        alert(response);
    });
    return false;
}

或

jQuery(document).ready(function(){ var newbie = function(email) { var data = { action: 'test_response', post_var: email }; // the_ajax_script.ajaxurl is a variable that will contain the url to the ajax processing file $.post(the_ajax_script.ajaxurl, data, function(response) { alert(response); }); return false; } var email = 'emailaddress'; newbie(email); });

Answer 2

javascript中的函数采用'参数'。您可以传入所需的参数，并在函数声明中定义其名称空间。即

function foo(bar,baz,etc){
   console.log(bar,baz,etc);
}
foo(1,2,3)
 //logs out 1 2 3

有时你并不总是知道将要传入的内容或将会有多少个参数，在这种情况下，在函数声明中我们可以使用'arguments'对象来挑选传递给它的某些参数。功能

function foo(){
   console.log(arguments);
}
foo(1,2,3)
 //logs out an array object that looks like this [1,2,3]

Answer 3

jQuery（document）.ready（function newbie（$，email）{

//var email = 'emailaddress'
var data = {
    action: 'test_response',
    post_var: email
};
// the_ajax_script.ajaxurl is a variable that will contain the url to the ajax processing file
$.post(the_ajax_script.ajaxurl, data, function(response) {
    alert(response);
});
return false;

}）;

您只需通过传递值

来调用该函数

将变量传递给JavaScript函数
