trim

From my experiments, it does not appear to do so. If this is indeed true, what is the best method for removing line breaks? I'm currently experimenting with the parameters that TRIM accepts of the character to remove, starting with trimming \n and \r . Peter Crabtree Trim() in MySQL only removes spaces. I don't believe there is a built-in way to remove all kinds of trailing and leading whitespace in MySQL, unless you repeatedly use Trim() . I suggest you use another language to clean up your current data and simply make sure your inputs are sanitized from now on. My line breaks were in the

i am currently using this to get the url from the background-image property: var url = $(this).find('div').css('background-image'); url = url.substr(4, url.length - 5); This works fine however in some browser (IE6-9), instead of it being: url(http://.com/) its url("http://.com/) Is there a failsafe way that will just get the url from this property? without having to do browser detection or some other stuff? You could do: url = url.replace(/^url\(["']?/, '').replace(/["']?\)$/, ''); This will remove url(' and url(" from the beginning of the string if it is present and ") resp. ') from the end.

I am making use of trim() like so: if($('#group_field').val().trim()!=''){ Where group_field is an input element of type text. This works in Firefox but when I try it on IE8 it gives me this error: Message: Object doesn't support this property or method When I remove the trim(), it works fine on IE8. I thought the way I am using trim() is correct? Thanks all for any help Try this instead: if($.trim($('#group_field').val()) != ''){ More Info: http://api.jquery.com/jQuery.trim/ You should use $.trim , like this: if($.trim($('#group_field').val()) !='') { // ... } As far as I know, Javascript

Greetings everyone... I need to Trim a String . But I want to remove all the repeated blank spaces within the String itself, not only at the end or at the start of it. I could do it with a method like: public static string ConvertWhitespacesToSingleSpaces(string value) { value = Regex.Replace(value, @"\s+", " "); } Which I got from here . But I want this piece of code to be called within the String.Trim() itself, so I think I need to extend or overload or override the Trim method... Is there a way to do that? Thanks in advance. JoeyRobichaud Since you cannot extend string.Trim(). You could

Mybatis介绍 MyBatis( http://www.mybatis.org/ ) 是支持定制化 SQL、存储过程以及高级映射的优秀的持久层框架。MyBatis 避免了几乎所有的 JDBC 代码和手动设置参数以及获取结果集。MyBatis 可以对配置和原生Map使用简单的 XML 或注解，将接口和 Java 的 POJOs(Plain Old Java Objects,普通的 Java对象)映射成数据库中的记录。 动态 SQL 作用 MyBatis 的强大特性之一便是它的动态 SQL。如果你有使用 JDBC 或其他类似框架的经验，你就能体会到根据不同条件拼接 SQL 语句有多么痛苦。拼接的时候要确保不能忘了必要的空格，还要注意省掉列名列表最后的逗号。利用动态 SQL 这一特性可以彻底摆脱这种痛苦。 通常使用动态 SQL 不可能是独立的一部分,MyBatis 当然使用一种强大的动态 SQL 语言来改进这种情形,这种语言可以被用在任意的 SQL 映射语句中。 动态 SQL 元素和使用 JSTL 或其他类似基于 XML 的文本处理器相似。在 MyBatis 之前的版本中,有很多的元素需要来了解。MyBatis 3 大大提升了它们,现在用不到原先一半的元素就可以了。MyBatis 采用功能强大的基于 OGNL 的表达式来消除其他元素。 if 动态 SQL 通常要做的事情是有条件地包含
