嘿傢伙和GAL我有一些重大問題試圖讓我的應用程序工作。我一直試圖通過這個破解,我錯過了發送正確的輸入值(按鈕值)讓球滾動的第一部分,我敢肯定這是簡單的,但我一直有一個問題得到它工作。如果有人能挑出錯誤來幫助我,我會很感激。JQuery POST按鈕的值,返回輸入?
這是非常簡單的PHP做的,但由於這是一個獨立的離線 應用程序我不能使用PHP =(我需要做我的所有抓取和JQuery的 或JavaScript解析....
我們先從一些按鈕,具有獨特的價值一個非常基本的形式。
<form>
<fieldset>
<legend>Select Orders</legend>
<table id='master'></table>
</div> <!-- end input1 -->
<div>
<button name="select" type="submit" id="btnLoad" value="load">Refresh</button>
<button name="select" type="submit" id="btnJson" value="down">Download JSON</button>
<button name="select" type="submit" id="btnView" value="view">View/Enter</button>
</div>
</fieldset>
</form>
觸發該功能
$(function() {
$("form").submit(function() {
/* what obj are we recieving?
$.each($(this), function(index, obj) {
console.log('Index: ' + index + ' Obj: '+ obj);
// returns this B/S: Index: 0 Obj: [object HTMLFormElement]
});
*/
// $this.button.val() never makes it through?
queryJsonServer($(this), "class/");
return false;
});
});
像
var button = $(this).attr("value");
var button = $('button').attr("value"); // ends up with the first buttons value,
// but never the selected or $(this).val()
$('button').click(function() { // which WILL console.log the buttons val,
console.log($(this).val()); // but will not let me turn it into a var?
return false; // ALSO this looks like it only reads the
}); // value the SECOND click?
的使命這裏我試過的東西是發送按鈕值作爲$ _POST輸入到解析器將返回相應的JSON數組解析,或者存儲在一個本地SQLite數據庫。
無論哪種方式,這裏是頁面的完整代碼,有人可以給我一個手,或者如果我需要澄清,請讓我知道。

你的問題的範圍。你的狀態變量是本地的,並且在點擊功能之外什麼都不做。 – adeneo 2012-02-20 19:46:42
