<span class='line'> 11</span> This file creates a global JSON object containing two methods: stringify
<span class='line'> 12</span> and parse.
<span class='line'> 13</span>
<span class='line'> 14</span> JSON.stringify(value, replacer, space)
<span class='line'> 15</span> value any JavaScript value, usually an object or array.
<span class='line'> 16</span>
<span class='line'> 17</span> replacer an optional parameter that determines how object
<span class='line'> 18</span> values are stringified for objects. It can be a
<span class='line'> 19</span> function or an array of strings.
<span class='line'> 20</span>
<span class='line'> 21</span> space an optional parameter that specifies the indentation
<span class='line'> 22</span> of nested structures. If it is omitted, the text will
<span class='line'> 23</span> be packed without extra whitespace. If it is a number,
<span class='line'> 24</span> it will specify the number of spaces to indent at each
<span class='line'> 25</span> level. If it is a string (such as '\t' or '&nbsp;'),
<span class='line'> 26</span> it contains the characters used to indent at each level.
<span class='line'> 27</span>
<span class='line'> 28</span> This method produces a JSON text from a JavaScript value.
<span class='line'> 29</span>
<span class='line'> 30</span> When an object value is found, if the object contains a toJSON
<span class='line'> 31</span> method, its toJSON method will be called and the result will be
<span class='line'> 32</span> stringified. A toJSON method does not serialize: it returns the
<span class='line'> 33</span> value represented by the name/value pair that should be serialized,
<span class='line'> 34</span> or undefined if nothing should be serialized. The toJSON method
<span class='line'> 35</span> will be passed the key associated with the value, and this will be
<span class='line'> 36</span> bound to the value
<span class='line'> 37</span>
<span class='line'> 38</span> For example, this would serialize Dates as ISO strings.
<span class='line'> 39</span>
<span class='line'> 40</span> Date.prototype.toJSON = function (key) {
<span class='line'> 41</span> function f(n) {
<span class='line'> 42</span> // Format integers to have at least two digits.
<span class='line'> 43</span> return n &lt; 10 ? '0' + n : n;
<span class='line'> 44</span> }
<span class='line'> 45</span>
<span class='line'> 46</span> return this.getUTCFullYear() + '-' +
<span class='line'> 47</span> f(this.getUTCMonth() + 1) + '-' +
<span class='line'> 48</span> f(this.getUTCDate()) + 'T' +
<span class='line'> 49</span> f(this.getUTCHours()) + ':' +
<span class='line'> 50</span> f(this.getUTCMinutes()) + ':' +
<span class='line'> 51</span> f(this.getUTCSeconds()) + 'Z';
<span class='line'> 52</span> };
<span class='line'> 53</span>
<span class='line'> 54</span> You can provide an optional replacer method. It will be passed the
<span class='line'> 55</span> key and value of each member, with this bound to the containing
<span class='line'> 56</span> object. The value that is returned from your method will be
<span class='line'> 57</span> serialized. If your method returns undefined, then the member will
<span class='line'> 58</span> be excluded from the serialization.
<span class='line'> 59</span>
<span class='line'> 60</span> If the replacer parameter is an array of strings, then it will be
<span class='line'> 61</span> used to select the members to be serialized. It filters the results
<span class='line'> 62</span> such that only members with keys listed in the replacer array are
<span class='line'> 63</span> stringified.
<span class='line'> 64</span>
<span class='line'> 65</span> Values that do not have JSON representations, such as undefined or
<span class='line'> 66</span> functions, will not be serialized. Such values in objects will be
<span class='line'> 67</span> dropped; in arrays they will be replaced with null. You can use
<span class='line'> 68</span> a replacer function to replace those with JSON values.
<span class='line'> 69</span> JSON.stringify(undefined) returns undefined.
<span class='line'> 70</span>
<span class='line'> 71</span> The optional space parameter produces a stringification of the
<span class='line'> 72</span> value that is filled with line breaks and indentation to make it
<span class='line'> 73</span> easier to read.
<span class='line'> 74</span>
<span class='line'> 75</span> If the space parameter is a non-empty string, then that string will
<span class='line'> 76</span> be used for indentation. If the space parameter is a number, then
<span class='line'> 77</span> the indentation will be that many spaces.
<span class='line'> 78</span>
<span class='line'> 79</span> Example:
<span class='line'> 80</span>
<span class='line'> 81</span> text = JSON.stringify(['e', {pluribus: 'unum'}]);
<span class='line'> 82</span> // text is '["e",{"pluribus":"unum"}]'
<span class='line'> 83</span>
<span class='line'> 84</span>
<span class='line'> 85</span> text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
<span class='line'> 86</span> // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
<span class='line'> 87</span>
<span class='line'> 88</span> text = JSON.stringify([new Date()], function (key, value) {
<span class='line'> 89</span> return this[key] instanceof Date ?
<span class='line'> 90</span> 'Date(' + this[key] + ')' : value;
<span class='line'> 91</span> });
<span class='line'> 92</span> // text is '["Date(---current time---)"]'
<span class='line'> 93</span>
<span class='line'> 94</span>
<span class='line'> 95</span> JSON.parse(text, reviver)
<span class='line'> 96</span> This method parses a JSON text to produce an object or array.
<span class='line'> 97</span> It can throw a SyntaxError exception.
<span class='line'> 98</span>
<span class='line'> 99</span> The optional reviver parameter is a function that can filter and
<span class='line'>100</span> transform the results. It receives each of the keys and values,
<span class='line'>101</span> and its return value is used instead of the original value.
<span class='line'>102</span> If it returns what it received, then the structure is not modified.
<span class='line'>103</span> If it returns undefined then the member is deleted.
<span class='line'>104</span>
<span class='line'>105</span> Example:
<span class='line'>106</span>
<span class='line'>107</span> // Parse the text. Values that look like ISO date strings will
<span class='line'>108</span> // be converted to Date objects.
<span class='line'>109</span>
<span class='line'>110</span> myData = JSON.parse(text, function (key, value) {
<span class='line'>111</span> var a;
<span class='line'>112</span> if (typeof value === 'string') {
<span class='line'>113</span> a =
<span class='line'>114</span> /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
<span class='line'>115</span> if (a) {
<span class='line'>116</span> return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
<span class='line'>117</span> +a[5], +a[6]));
<span class='line'>118</span> }
<span class='line'>119</span> }
<span class='line'>120</span> return value;
<span class='line'>121</span> });
<span class='line'>122</span>
<span class='line'>123</span> myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
<span class='line'>124</span> var d;
<span class='line'>125</span> if (typeof value === 'string' &&
