在這里，我正在準(zhǔn)備 formData 值并將其存儲(chǔ)到一個(gè)隱藏變量中。所以我想刪除添加到res變量中的值。有什么想法嗎？我試過(guò) formData.delete(pair[0]);...沒(méi)用function prepareOCPDepEntries(isButton){ var formEl = document.forms.mainForm; var formData = new FormData(formEl); var res = ""; for(var pair of formData.entries()) { if(pair[0].startsWith("_")){ res = res +"|"+ pair; formData.delete(pair[0]); } } document.getElementById("depEntry").value = res; document.forms.mainForm.disabled = true;}HTML代碼；對(duì) [0] 將是 _0.0<select name="_0.0" id="_0.0" ><option value="1" >Y</option><option value="0" selected>N</option><option value="2" >A</option><option value="3" >T1</option><option value="4" >T2</option><option value="5" >T3</option></select></TD><select name="_0.1" id="_0.2" ><option value="1" >Y</option><option value="0" selected>N</option><option value="2" >A</option><option value="3" >T1</option><option value="4" >T2</option><option value="5" >T3</option></select></TD>
如何在 java 腳本中提交之前從 formData 中刪除值
