如何將動態字符串數組從javascript傳遞到JSON對象

Question

function createNew(mouseEventData) {
 var measurementData = {
            visible: true,
            active: true,
            toolType: 'target',
            description: output
        };

        return measurementData;
}

 function onImageRendered(e, eventData) {
    var textline = ["Test"];
    var obj = { "description":textline};
    alert(obj)//[object Object]
    var output = JSON.stringify(obj);
    alert("output"+output); //output{"description":["Test"]}
}

在上面的代碼片段中，我想將文本行字符串數組傳遞給measurementData的描述字段。 請幫助我如何將動態字符串數組傳遞給JSON對象（文本行是動態數組）

Answer 1

您可以只使用全局變量：

var measurementData;

function createNew(mouseEventData) {
    return measurementData;
}

function onImageRendered(e, eventData) {
    var textline = ["Test"];
    measurementData = {
        visible: true,
        active: true,
        toolType: 'target',
        description: textline
    };
}
