Class Ext.util.Format

Parse a value into a formatted date using the specified format pattern.

Truncate a string and add an ellipsis ('...') to the end if it exceeds the specified length

<static> Escapes the passed string for ' and \

Escapes the passed string for use in a regular expression

<static> Allows you to define a tokenized string and pass an arbitrary number of arguments to replace the tokens. Each token must be unique, and must increment in the format {0}, {1}, etc. Example usage:

var cls = 'my-class', text = 'Some text';
var s = Ext.util.Format.format('<div class="{0}">{1}</div>', cls, text);
// s now contains the string: '<div class="my-class">Some text</div>'

Convert certain characters (&, <, >, and ') from their HTML character equivalents.

Convert certain characters (&, <, >, and ') to their HTML character equivalents for literal display in web pages.

<static> Pads the left side of a string with a specified character. This is especially useful for normalizing number and date strings. Example usage:

var s = Ext.util.Format.leftPad('123', 5, '0');
// s now contains the string: '00123'

Utility function that allows you to easily switch a string between two alternating values. The passed value is compared to the current string, and if they are equal, the other value that was passed in is returned. If they are already different, the first value passed in is returned. Note that this method returns the new value but does not change the current string.

// alternate sort directions
    sort = Ext.util.Format.toggle(sort, 'ASC', 'DESC');

    // instead of conditional logic:
    sort = (sort == 'ASC' ? 'DESC' : 'ASC');

Trims whitespace from either end of a string, leaving spaces within the string intact. Example:

var s = '  foo bar  ';
    alert('-' + s + '-');         //alerts "- foo bar -"
    alert('-' + Ext.util.Format.trim(s) + '-');  //alerts "-foo bar-"
