When the amount of data is not very large and there is no functional interface corresponding to the back-end, some simple search functions are basically implemented by the front-end. I happened to use it recently, so I wrote one and posted it to share with everyone:

Rendering:

Function description:

After pressing the keyboard, search for the Chinese characters in the entry, the corresponding pinyin and number of the Chinese characters;

Implementation ideas:

First convert the Chinese characters in the entry into Pinyin, then splice the Chinese characters, Pinyin, and numbers into a regular string, put it into an array, and then determine whether the value in the input is a Chinese character, Pinyin, or a number each time you press the keyboard. , and then loop through the array according to a fixed rule, so that the corresponding entry can be found;

Activation method:

// search-test-inner ---> Outermost div
// search-value ---> input input box
// search-value-list ---> Search results display div
// search-li ---> Search items
new SEARCH_ENGINE("search-test-inner","search-value","search-value-list","search-li");
Note: The search entry plus two temporary data, data-name and data-phone, are used to store Chinese characters and numbers.

Note: Pinyin conversion uses a plug-in called jQuery.Hz2Py-min.js. Since this plug-in can only convert the value in the input, there is an extra step in the code. First, put the value into a temporary input. , and then convert.

CSS:

复制代码代码如下:

* { padding: 0; margin: 0; }

ol , ul { list-style: none; }

body { font-size: 12px; color:#333; }

.search-test-inner { margin: 100px auto; padding: 10px; width: 400px; background: #e0e0e0; border-radius: 10px; box-shadow: 1px 2px 6px #444; }

.search-val-inner { margin-bottom: 20px; padding: 10px; background: #fff; }

.member-list-inner .search-li { padding: 10px; }

.search-value-list { margin-top: 10px; }

.search-value-list li { padding: 5px; }

.member-list-inner .search-li .phone,

.search-value-list li .phone { float: right; }

.search-value { width: 100%; height: 30px; line-height: 30px; }

.tips { font-weight: bold; }

JS:

复制代码代码如下:

         $pinyin.remove();

            }
            else{
                searchEngine.searchResultInner.html('

');
            }
              searchEngine.postMemberList(tempArray);
        });
}
};

Isn’t the effect great? Friends, you can use it in your own projects after beautifying it
