What is fuzzy query in php
1. In php, we often use drop-down boxes and they are related to each other. If there are many options in the drop-down box, then we have to use the fuzzy search function. So how to do it?
In this function, we have taken a detour. It is best not to associate the id values of two selects and then the select attribute is selected and cannot be modified. Remove the attribute when selecting again. This will cause Firefox and Google js compatibility issues when removing the select attribute. It is easy to have non-correspondence or attributes that cannot be removed, and the functions are troublesome. In addition, the corresponding relationship between the two must be judged in the background. (When comparing the correspondence between the two in the background, you have to go to the database to query, find the company's ID, and go to the database to query the guarantee company's ID comparison. Do not use the front desk to get the guarantee company's ID value).
2. Style:
# are related to each other. If there is a guarantee company, the drop-down box will only display one guarantee company, and the others will not be displayed. If there is no guarantee company, the drop-down box will not display the guarantee company. , display all, and let the administrator choose.
3. We know that the select drop-down box is not allowed to have a search box, and we cannot write an input search box in it, so we can only use Plug-in to implement, convert the select box into ul li, very easy to use plug-in: select2.
4. Normally obtain data in the background database and assign values; and introduce the select2 plug-in. Note that the css files related to the select2 plug-in must also be imported. Some css for asking prices and js are encapsulated, and the styles can be changed by yourself.
.select2-results__option[aria-selected] {
cursor: pointer;
font-size: 14px;
}
.select2-container--default .select2-selection--single .select2-selection__rendered {
color: #444;
line-height: 28px;
font-size:14px;
}
.select2-container--default .select2-results > .select2-results__options {
max-height: 280px;
overflow-y: auto;
}
