Editor to share with you how to use php jquery, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

JavaScript code

Function lookup (inputString) {

If (inputString.length==0) {

/ / Hide the suggestion box.

('# suggestions'). Hide ()

} else {

$.post ("rpc.php", {queryString: "" + inputString+ ""}, function (data) {

If (data.length > 0) {

('# suggestions'). Show ()

$('# autoSuggestionsList') .html (data)

}

})

}

} / / lookup

Function fill (thisValue) {

$('# inputString') .val (thisValue)

('# suggestions'). Hide ()

}

JS's interpretation

Well, as you can see from the code above, we need to connect to a file called rpc.php, which handles all the operations.

The lookup function uses the word obtained from the text input box and then passes it to rpc.php using the method POST of Ajax in jQuery.

If the character 'inputString'' is'0', the suggestion box is hidden, which is also very human, and you don't expect a prompt box if you don't type anything in the search box.

If there is something in the input box, we get this' inputString' and pass it to the rpc.php page, and then the $. Post () function of jQuery is used, as follows:

$.post (url, [data], [callback])

The callback' section can associate a function, which is interesting and will be executed only when the data is loaded successfully.

If the returned data (data) is not empty (that is, something to display), display the search prompt box and replace the html code with the returned data (data).
