本文執行個體講述了JS更改select內option屬性的方法。分享給大家供大家參考。具體如下：
幫一位友人解決了一個小問題，需求是更改選中選項卡內顯示的文本值，新值存放在某個文字框內
初始視窗：
<html> <head> <title>原視窗</title> <script> var parentValue=""; //全域變數，用於儲存點擊詳情時select中指定opeion的值 function detail() { var select=document.getElementById('SHGX'); //獲得select對象 parentValue=select.options[select.selectedIndex].text; window.open('詳情視窗.html') } function updateSelect(childValue) { var select=document.getElementById('SHGX'); for(var i=0;i<select.length;i++) { if(select.options[i].text==parentValue) select.options[i].text=childValue; } } </script> </head> <body> <select id='SHGX'> <option value='111' title='夫'>夫</option> <option value='112' title='妻'>妻</option> <option value='120' title='子'>子</option> <option value='121' title='獨生子'>獨生子</option> <option value='122' title='繼子'>繼子</option> <option value='128' title='女婿'>女婿</option> </select> <button onclick="detail(); ">詳情</button> </body></html>
詳情視窗：
<html> <head> <title>詳情視窗</title> <script> function modify() { var childValue=document.getElementById('text_01').value; opener.updateSelect(childValue); //調用父視窗的函數 } </script> </head> <body> <input id="text_01" type="text" value=""/> <button onclick="modify();">修改</button> </body></html>
希望本文所述對大家的JavaScript程式設計有所協助。
