When I was writing code today, I used ajax to obtain data asynchronously. Everything was normal under Firefox 13.0. However, when IE6 was tested under various versions of IE, it was normal, but IE8 reported an error "Error: This is caused by the error c00ce56e. The operation could not be completed". Because Firefox is the browser I use to write code and do testing, I usually ensure the correctness under it first. Everything looks so normal under Firefox.
My environment is: the js code is based on jQuery, using asynchronous loading to load each js class library, the request method is 'GET', and the return format is 'html';
Since the previous work has been completed in stages, I am going to check whether it is normal under IE. At first glance, I am a bit depressed and there is no response. The data is not displayed. Then under IE, F13, I found that there was no problem with the process of requesting data under IE, and the data was also obtained in the control panel, but when I used $('#id').html(data); to insert data into the DOM , completely unresponsive.
Continue debugging, and then in the error parameter option of the $.ajax request, when I alerted the errorThrown parameter passed to the callback function, I got the following error: "This operation cannot be completed due to the error c00ce56e.", This is critical because the error that pops up has a code, so it is a traceable error.
By the way, the ajax request under Firefox returns success, but under IE, it returns error. Based on this error message, I searched for relevant answers on the Internet and found a more useful statement that the encoding is inconsistent. After searching, I found that the encoding of my html page is utf-8, and the setting in my php program is also header('Content-type: text/html;charset=utf-8'); This is all depressing, the same There is no problem. Later, when I checked the source code of the page, I found out why it was utf8. Where did the missing '-' go? I later discovered that charset utf8 was set in the nginx configuration; the forced character encoding is utf8. , quickly restarted nginx and everything was normal. . .
Based on this question, the following experience can be summarized:
Firefox has stronger fault tolerance than IE. In terms of HTML5 design ideas, Firefox performs better. Whether such fault tolerance will cause security risks is unknown because it has not been tested;
Try to keep the various encodings of the program consistent, otherwise unpredictable errors may occur. It is recommended to use utf-8;

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
