+# URL字符串解析
+
+### 简介
+
+本示例对URL字符串的查找参数进行了增删改查的一系列操作，使得读者对URL的结构用途更加明了。
+
+### 使用说明
+
+1.点击**URLSearchParamsConstruct**按钮，文本框会呈现出URL查找参数的四种构造方法。
+
+2.点击**Insert**按钮，会将左面文本框的参数插入到查找参数后面。
+
+3.点击**delete**按钮，会将同参数名相关参数全部删除于查找参数之中，并输出在文本框中。
+
+4.点击**getAll**按钮，会将查找参数中所有同名的参数值依次排列显示。
+
+5.点击**getFirst**按钮，会将查找参数中该参数名的第一个参数值显示出来。
+
+6.点击**setValue**按钮，将与名称关联的URL搜索参数对象中的值进行重新赋值。如果存在名称为name的键值对，请将第一个键值对的值重新赋值并删除所有其他值。如果不是，则将键值对附加到查询字符串。
+
+7.点击**Sort**按钮，对包含在此对象中的所有键值对进行排序。排序顺序是根据键的Unicode代码点。该方法使用稳定的排序算法 （即，将保留具有相等键的键值对之间的相对顺序）。
+
+### 约束与限制
+
+本示例仅支持在标准系统上运行。
