Combined Use of Javascript and select components

<? Php

// Use Javascript and select components in combination
// In the process of writing a program, after selecting the select object option,
// You do not need to submit a button, but directly trigger the action.
// To keep the selected options on the page. Finally
// Use the onchange attribute and
// Value to implement this function.
// The Code is as follows (the file name is "test. php "):


Switch ($ mon ){
Case: echo select your constellation:; break;
Case 1: echo your constellation is Aquarius; break;
Case 2: echo your constellation is Pisces; break;
Case 3: echo your constellation is Aries; break;
Case 4: echo your constellation is Taurus; break;
Case 5: echo your constellation is Gemini; break;
Case 6: echo your constellation is cancer; break;
Case 7: echo your constellation is Leo; break;
Case 8: echo your constellation is Virgo; break;
Case 9: echo your constellation is Tianping; break;
Case 10: echo your constellation is Scorpio; break;
Case 11: echo your constellation is Sagittarius; break;
Case 12: echo your constellation is Capricorn; break;
Default: break;
