javascript - 如何在javascript中调用另一个函数？

Question

当确认消息框为 true 时，如何从 conFirmUpload() 调用 doSubmit() 函数？

<script type="text/javascript">
    function confirmUpload() {
        if (confirm("Are you sure want to upload '" + document.getElementById("txtWS").value + "' ?") == true) {
            return true;
        }
        else
            return false;
    }

    function doSubmit(btnUpload) {
        if (typeof(Page_ClientValidate) == 'function' && Page_ClientValidate() == false) { 
            return false;
        }    
        btnUpload.disabled = 'disabled';
        btnUpload.value = 'Processing. This may take several minutes...';
        <%= ClientScript.GetPostBackEventReference(btnUpload, string.Empty) %>;    
    }
</script>

Answer 1

var btnUpload = document.getElementById('buttonId');
doSubmit(btnUpload);

将其放入 if block 中。确保该按钮有一个 ID。
