Prototype 字符串处理：方法操作使用例子 - 学习如何操纵DOM和AJAX使用Prototype JavaScript框架.Prototype提高了一个有用的方法，从琐碎的一系列复杂的String对象.
这里是所有函数列表，字符串处理的例子.
Prototype字符串方法:
注: 确保你有至少1.6版本的的prototype.js.
| Methods | Description |
|---|---|
| blank() | 检查是否该字符串是“空白”，意思是空的或含有唯一的空白. |

| empty() | Checks if the string is empty. |
| endsWith() | Checks if the string ends with substring. |
| escapeHTML() | Converts HTML special characters to their entity equivalents. |
| evalJSON() | Evaluates the JSON in the string and returns the resulting object. |
| evalScripts() | Evaluates the content of any script block present in the string. Returns an array containing the value returned by each script. |
| extractScripts() | Extracts the content of any script block present in the string and returns them as an array of strings. |
| gsub() | Returns the string with every occurrence of a given pattern replaced by either a regular string, the returned value of a function or a Template string. |
| include() | Check if the string contains a substring. |
| inspect() | Returns a debug-oriented version of the string. |
| interpolate() | Treats the string as a Template and fills it with object's properties. |
| isJSON() | Check if the string is valid JSON by the use of regular expressions. This security method is called internally. |
| parseQuery() | Parses a URI-like query string and returns an object composed of parameter/value pairs. |
| scan() | Allows iterating over every occurrence of the given pattern |
| startsWith() | Checks if the string starts with substring. |
| strip() | Strips all leading and trailing whitespace from a string. |
| stripScripts() | Strips a string of anything that looks like an HTML script block. |
| stripTags() | Strips a string of any HTML tag. |
| sub() | Returns a string with the first count occurrences of pattern replaced by either a regular string, the returned value of a function or a Template string. |
| succ() | Used internally by ObjectRange. Converts the last character of the string to the following character in the Unicode alphabet. |
| times() | Concatenates the string count times. |
| toArray() | Splits the string character-by-character and returns an array with the result. |
| toJSON() | Returns a JSON string. |
| toQueryParams() | Parses a URI-like query string and returns an object composed of parameter/value pairs. |
| truncate() | Truncates a string to the given length and appends a suffix to it (indicating that it is only an excerpt). |
| underscore() | Converts a camelized string into a series of words separated by an underscore ("_"). |
