jQuery Form 插件基于jQuery v1.4.2版返回JSON數據時一直報錯;修改以下內容可恢復;
原后臺輸出數據格式如:{sitename:'開發者網絡',siteurl:'www.AAA.net',level:10} 需改為 {"sitename":"開發者網絡","siteurl":"www.AAA.net","level":10}
也就是在名稱需以雙引號包括;因為 jQuery 1.4.2版在 parseJSON 方法中添加了正則判斷
if ( /^[\],:{}\s]*$/.test(data.replace(/\\(?:["\\\/bfnrt]|u[0-9a-fA-F]{4})/g, "@")
.replace(/"[^"\\\n\r]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g, "]")
.replace(/(?:^|:|,)(?:\s*\[)+/g, "")) ) {
// Try to use the native JSON parser first
return window.JSON && window.JSON.parse ?
window.JSON.parse( data ) :
(new Function("return " + data))();
} else {
jQuery.error( "Invalid JSON: " + data );
}
jQuery Form 插件需要修改的地方
if (scr || s.textarea) {
// see if user embedded response in textarea
var ta = doc.getElementsByTagName('textarea')[0];
if (ta) {
xhr.responseText = ta.value;
}
else if (scr) {
// account for browsers injecting pre around json response
var pre = doc.getElementsByTagName('pre')[0];
if (pre) {
xhr.responseText = pre.innerHTML;
}
}
}
else if (s.dataType == 'xml' && !xhr.responseXML && xhr.responseText != null) {
xhr.responseXML = toXml(xhr.responseText);
}
修改為:
if (scr || s.textarea) {
// see if user embedded response in textarea
var ta = doc.getElementsByTagName('textarea')[0];
if (ta) {
xhr.responseText = ta.value;
}
else if (scr) {
// account for browsers injecting pre around json response
var pre = doc.getElementsByTagName('pre')[0];
if (pre) {
xhr.responseText = pre.innerHTML;
}else xhr.responseText=doc.body.innerHTML;
}
}
else if (s.dataType == 'xml' && !xhr.responseXML && xhr.responseText != null) {
xhr.responseXML = toXml(xhr.responseText);
}
