[英]Jira Gadget - Reload AJAX on Config Screen
在任何地方都找不到解決方案,我真的希望有可能。
我正在編寫一個Jira小工具,並且有一個包含2個字段的配置屏幕。 一種是快速查找項目選擇器; 您鍵入並找到項目,然后單擊所需的項目。
第二個字段是組件。 您可以選擇要過濾的項目組件。 但是,每個項目的組件都不相同,因此“組件”字段將使用在“配置”部分的“參數”部分中的小工具中指定的AJAX調用填充。
唯一的問題是,僅在首次加載小工具時才調用此AJAX。 即:在選擇項目之前,結果始終為“選擇項目”。
我需要一種方法來在所選項目發生更改時重新運行此AJAX調用。
這可能嗎? 還是有替代解決方案? 我已經嘗試使用計時器來檢查更改,但是那里也存在一些問題。 主要是我無法訪問/更改“組件”下拉框字段。 該小工具只會拒絕加載。
更新:以下是該小工具的Javascript。 如您所見,我添加了refreshComponents()
Javascript方法,該方法可以在給定項目ID的情況下檢索組件,但是我無法將其附加到適當的事件。 而且我似乎無法像jQuery或普通JS這樣直接更改頁面上的任何組件

我認為您需要將您的component字段轉換為Callback Builder 。
在回調函數內部,您需要做一些事情:
您的新component字段可能看起來像這樣...為了簡化起見,我假設您可以使用jQuery。
{
userpref: "component",
label: "Component",
id: "component_field_id"
description: "Choose which issue type you would like",
type: "callbackBuilder",
callback: function(parentDiv){
function renderOptions(options){
// Remove elements from the parentDiv and replace them
// with new elements based on the options param
// You can use gadget.getPref('component') to ensure you
// mark the right option as selected
}
function getOptions(){
$.ajax({
url: "__ATLASSIAN_BASE_URL__/rest/severity-gadget/1.0/severity-issues/getComponents.json",
data: {
// You might be able to get hold of the selected value
// from the gadget object instead of like this
projectId: $("#filter_projectOrFilterId_id").val()
}
}).done(renderOptions);
}
// Retrieve and render options on gadget load
getOptions();
// Retrieve and render options on an event
$(parentDiv).on("update-options", getOptions);
}
}
另外,您需要在項目選擇字段值更改時觸發事件。 您需要在JS代碼中的其他位置(不在小工具定義中)放入這樣的代碼,但是您需要確認project / filter選擇器的CSS選擇器:
$(document).on("change", "#filter_projectOrFilterId_id", function(){
$("#component_field_id").trigger("update-options");
});
我尚未對此進行測試,但這就是我試圖實現您所要求的方式。
