我不明白为什么我会收到此错误。我正在使用 cfform 将数据从一个 html 页面发送到下一个。见下文。我注意到的另一件事是 angle_changes 字符串的前两个字符被截断。它应该是“0a0a0a0a”，但错误消息中传递了“0a0a0a”。
以下是来自spatialforaging.cfm的相关html/Javascript代码：
<!---all of these get passed from a previous page using cfoutput, except for angle_changes--->
<cfform action="field_transition.cfm" method="post" name="field_form">
<cfinput type="hidden" id="angle_changes" name="angle_changes" value="">
<cfinput type="hidden" id="subject_id" name="subject_id" value=#subject_id#>
<cfinput type="hidden" id="times_switched_away" name="times_switched_away" value=#times_switched_away#>
<cfinput type="hidden" id="total_time_unfocused" name="total_time_unfocused" value=#total_time_unfocused#>
<cfinput type="hidden" id="completed_fields" name="completed_fields" value="">
</cfform>
脚本
//these values get changed earlier in the script
document.getElementById("times_switched_away").value = times_switched_away;
document.getElementById("total_time_unfocused").value = total_time_unfocused;
document.getElementById("completed_fields").value = completed_fields.toString();
//angleChanges is an array containing integers which is created elsewhere …
