本文实例讲述了js实现接收表单的值并将值拼在表单action后面的方法。分享给大家供大家参考，具体如下：

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 id="myform" name="myform" method="post" action="http://posed",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 class="btn-bar"> <input type="button" onClick="submitForm()" 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……"; 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

希望本文所述对大家JavaScript程序设计有所帮助。
