jQuery的发送数据与转义? [英] jquery sending data with escapes?
问题描述
我听说当我使用jQuery.ajax并将数据作为对象发送时-它会自动-逃脱字符.
I heard that when i use jQuery.ajax and sending data as object - it automatically - escapes the chars.
它写在哪里? 我在文档中找不到它
where does it written ? I didnt find it in Documentation
是真的吗?
推荐答案
在源代码中,定义了本地函数add
:
Inside the source code, a local function add
is defined:
add = function( key, value ) {
value = jQuery.isFunction( value ) ? value() : value;
s[ s.length ] = encodeURIComponent( key ) + "=" + encodeURIComponent( value );
};
此功能通过转义特殊字符来准备任何输入.当将对象作为参数传递时,将调用buildParams
方法,并传递刚刚定义的add
函数:
This function prepares any input by escaping the special characters. When an object is passed as an argument, the buildParams
method is invoked, passing the just-defined add
function:
for ( var prefix in a ) {
buildParams( prefix, a[ prefix ], traditional, add );
}
在递归函数 buildParams
中,为每个对象参数调用add
方法.口味有所不同,但通常采用以下格式:
Inside the recursive function buildParams
, the add
method is invoked for each object-parameter. The flavours differ, but are generally in the following format:
add( prefix, obj );
相关代码,这些代码源自 源代码 :
Relevant code, derived from the source code:
// Serialize an array of form elements or a set of
// key/values into a query string
param: function( a, traditional ) {
var s = [],
add = function( key, value ) {
// If value is a function, invoke it and return its value
value = jQuery.isFunction( value ) ? value() : value;
s[ s.length ] = encodeURIComponent( key ) + "=" + encodeURIComponent( value );
};
// Set traditional to true for jQuery <= 1.3.2 behavior.
if ( traditional === undefined ) {
traditional = jQuery.ajaxSettings.traditional;
}
// If an array was passed in, assume that it is an array of form elements.
if ( jQuery.isArray( a ) || ( a.jquery && !jQuery.isPlainObject( a ) ) ) {
// Serialize the form elements
jQuery.each( a, function() {
add( this.name, this.value );
});
} else {
// If traditional, encode the "old" way (the way 1.3.2 or older
// did it), otherwise encode params recursively.
for ( var prefix in a ) {
buildParams( prefix, a[ prefix ], traditional, add );
}
}
// Return the resulting serialization
return s.join( "&" ).replace( r20, "+" );
}
});
function buildParams( prefix, obj, traditional, add ) {
if ( jQuery.isArray( obj ) ) {
// Serialize array item.
jQuery.each( obj, function( i, v ) {
if ( traditional || rbracket.test( prefix ) ) {
// Treat each array item as a scalar.
add( prefix, v );
} else {
// If array item is non-scalar (array or object), encode its
// numeric index to resolve deserialization ambiguity issues.
// Note that rack (as of 1.0.0) can't currently deserialize
// nested arrays properly, and attempting to do so may cause
// a server error. Possible fixes are to modify rack's
// deserialization algorithm or to provide an option or flag
// to force array serialization to be shallow.
buildParams( prefix + "[" + ( typeof v === "object" || jQuery.isArray(v) ? i : "" ) + "]", v, traditional, add );
}
});
} else if ( !traditional && obj != null && typeof obj === "object" ) {
// Serialize object item.
for ( var name in obj ) {
buildParams( prefix + "[" + name + "]", obj[ name ], traditional, add );
}
} else {
// Serialize scalar item.
add( prefix, obj );
}
}
