我想一个名字发送:值对jQuery中使用$。员额对象,其中两个名称和值是变量的PHP脚本。我发出的变量在FF的控制台上,所以我知道他们正在设置正确,但是当我查看头被发送,只有变量的值被正确评估,这个名字被发送作为变量的文本字符串名称。下面是函数在其全部:
I am trying to send a name:value pair to a php script using the $.post object in jQuery where both name and value are variables. I have sent the variables to the console in FF, so I know they are being set correctly, but when I view the headers being sent, only the value variable is being evaluated correctly, the name is being sent as a literal string of the variable name. Here is the function in its entirely:
$(document).ready(function() {
$('#formS form fieldset > input').blur(function() {
if($(this).val()=='' && $(this).prev().is('img')) {
$(this).prev().remove();
return;
}
if((($(this).is('#formS form fieldset > input[id*=mail]')) ||
($(this).is('#formS form fieldset > input[id*=sername]'))) &&
($(this).val()!="")) {
var email_field = $(this);
if(!$(this).prev().is('img')){
$('<img src="" alt="" style="width: 16px; height: 16px;" />').insertBefore(this);
}
var type = ($(this).is('input[id*=sername]'))?'username':'email';
var value = $(this).val();
$.post('checkemail.php5', {type:value}, function(data) {
if(data == "free") {
email_field.prev().attr('src','/images/greentick.png').attr('alt','available');
} else if(data == "taken") {
email_field.prev().attr('src','/images/redcross.png').attr('alt','taken');
} else {
console.log('hmmm'+data);
}
});
}
});
});
因此,所发送的报头都是文字串键入,和任何的值的计算结果为。任何人有任何想法,为什么?
So, the headers being sent are the literal string type, and whatever value evaluates to. Anybody have any ideas why?
由于语法{}采用一组名称:值,其中名字成为对象的属性。这是文字的,不能是一个变量,如你所见。使用这样的:
Because the syntax {} takes a set of name:value where the names become the property on the object. This is a literal and cannot be a variable, as you see. Use this:
var params = {};
params[type] = value;
和传递PARAMS而不是{类型:值}
and pass params instead of {type:value}
