今天遇到一个问题，在form表单中有若干个input，其中有一个上传文件的input,现在需要在点击提交按钮时，将不是文件类型的input的值得到并拼成&name=value的格式加在action后面，这样就能一同传出去了
<form method="post" action="http://www.yoursiteweb.com:8080/justsy/Dolet?type=ws_justsy_webclips_policy_update" enctype="multipart/form-data"> <!-- 后台生成json --> <script type="text/javascript"> var data = [{label:"基本信息",type:"title",tag:"h1"}, {label:"Name",type:"input",input:"text",optional:false,name:"policyName",id:"policyName",value:""}, {label:"Description",type:"input",input:"text",optional:false,name:"policyDescription",id:"policyDescription",value:""}, {label:"",type:"title",tag:"h1"}, {label:"Label(Required)",type:"input", input:"text", optional:true, name:"Label",id:"Label",value:""}, {label:"URL(Required)",type:"input", input:"text", optional:true, name:"URL",id:"URL",value:""}, {label:"Removeable",type:"input", input:"checkbox", optional:false,name:"IsRemovable",id:"IsRemovable",value:"",accept:"image/* "}, {label:"Icon",type:"input", input:"file", optional:true, name:"picurl",id:"IconFile",value:""}, {label:"Precomposed Icon",type:"input", input:"checkbox",optional:false,name:"Precomposed",id:"Precomposed",value:""}, {label:"Full screen",type:"input", input:"checkbox",optional:false,name:"FullScreen",id:"FullScreen",value:""}, {type:"hidden",name:"policyID",id:"policyID",value:""}, {type:"hidden",name:"PayloadDescription",id:"PayloadDescription",value:""}, {type:"hidden",name:"PayloadDisplayName",id:"PayloadDisplayName",value:""}, {type:"hidden",name:"PayloadIdentifier",id:"PayloadIdentifier",value:""}, {type:"hidden",name:"PayloadOrganization",id:"PayloadOrganization",value:""}, {type:"hidden",name:"PayloadType",id:"PayloadType",value:""}, {type:"hidden",name:"PayloadUUID",id:"PayloadUUID",value:""}, {type:"hidden",name:"PayloadVersion",id:"PayloadVersion",value:""}, //{type:"hidden",name:"Icon",id:"Icon",value:""}, {type:"submit",optional:true,func:""} ]; inputs(data);//在需要显示输入框的地方调用该方法 </script> <div> <input type="button" value="保存"> </div> </form>
主要js代码：
function getParams() { var docList=document.getElementById("inputList").getElementsByTagName("input"); var str=""; //alert(docList.length) ; for(var i=0;i<docList.length-1;i++) { if(docList[i].getAttribute("type")=="checkbox"){ if(docList[i].checked) str+=getParam(docList[i].getAttribute("name"),"1") else str+=getParam(docList[i].getAttribute("name"),"0") } else str+=getParam(docList[i].getAttribute("name"),docList[i].value); } return str; } function getParam(key,value) { return "&"+key+"="+value; } function submitForm(){ if(document.getElementById("policyID").value == "") { alert("该公司没有创建策略"); return false; } else{ document.getElementById("IconFile_error").innerHTML="正在提交……"; /*获取文件上传的文件名称并且判断扩展名是否为JPG*/ var testmsg=document.getElementById("IconFile").value; var filename=testmsg.replace(/.*(\/|\\)/, ""); var fileExt=(/[.]/.exec(filename)) ? /[^.]+$/.exec(filename.toLowerCase()) : ''; if(fileExt!='jpg'){ document.getElementById("IconFile_error").innerHTML=""; alert("请上传图片"); return false; } document.getElementById("myform").action+=getParams(); document.getElementById("myform").submit(); } }
这样就能拼过去了....挺好用的....还能检验checkbox中的值...选中为1，不选中为0
