Question

我有以下功能（'submitTitle'），按下按钮时会调用该功能。我有两个单选按钮，由'submitTitle'动态生成。当用户选择“否”单选按钮时，它会触发一个匿名函数，该函数还在其中调用另一个名为“getIndexOfObject”的函数。我的问题是，我不断收到以下错误：'未捕获的ReferenceError：未定义getIndexofObject'，即使我已经定义了它。我不明白如何解决这个问题。

var titleArray = [];
UploadMyScript.submitTitle = function(id, callback){
    console.log('button '+id + ' pressed');



    //disable 'append' button.
    document.getElementById(id).disabled = true;

    var title_;
    var titleToAttach = document.getElementById('txtArea_'+id).value;

    if(titleToAttach == ''){
        console.log('Please enter a title for this pdf');
        // un-disable 'append' button
        document.getElementById(id).disabled = false;
    }else{

        /*HANDLE WEBSERVICE CALL HERE FOR EACH TITLE*/

        // Replace spaced in title with %20 (pubmed format for spaces)
        searchterm_ = encodeURI(titleToAttach);
        console.log('searchterm_: '+ searchterm_);

        //AJAX CALL
        var formdata = new FormData();
        formdata.append('titleSearchParam', searchterm_);

        // Create XMLHttprequest
        var xmlhttp = new XMLHttpRequest;
        console.log('pass0000');

        xmlhttp.onreadystatechange = function(){
            if(xmlhttp.readyState == 4 && xmlhttp.status == 200){

                console.log('greetings form inside onreadystate');

                /*RESPONSE TO AJAX CALL HERE*/
                var json_obj = JSON.parse(event.target.responseText);
                console.log('responseText: '+ event.target.responseText);



                var json_obj = JSON.parse(xmlhttp.responseText);
                console.log('responseText: '+ xmlhttp.responseText);

                if(json_obj == null || json_obj.title == null){
                    title_ = titleToAttach;
                    callback(id, title_);

                    console.log('null, title: ' + title_);

                }else{


                    .......

                    var radio_no = document.createElement('input');
                    radio_no.setAttribute('id', 'radio_no_'+id);
                    radio_no.type = 'radio';
                    radio_no.name = 'article';
                    radio_no.value = '0';
                    radio_no.addEventListener('click', function(){
                        // Remove this object from the titleArray
                        var indexOfObject = getIndexofObject(id, titleArray);
                        titleArray.splice(indexOfObject, 1);
                        console.log('titleArray below after splice: ');
                        console.log(titleArray);
                    });

                }
            }
        }
        xmlhttp.open("POST", "upload_myfiles.php");
        xmlhttp.send(formdata);
    }
}


 // Find the Index of a 'title_fileName' object in titleArray
function getIndexOfObject(id, array){
    var id_toMatch = UploadMyScript._('paraHeading_'+id).dataset.uniq_id;

    for(i=0; i< array.length ; i++){
        if(id_toMatch == array[i]['uniq_id']){
            return i;
        }   
    }
}

错误是正确的，未定义。

您正在调用getIndexofObject，函数名称为getIndexOfObject。

O已大写。

我定义的javascript函数无法识别
