``` <INPUT id="TextInput" style="width:100"> <INPUT id="TextOutPut" Name="TextInput"> <script type="text/javascript"> document.getElementById("TextOutPut").value =2； document.getElementById("TextInput").value =1； <script> ``` 写代码的时候一个突发奇想，因为输出时需要确认输入源，所以想在触发事件时通过Name属性记录输入源ID，再通过dom操作直接操作对应输入源。 设想这样的结果应该是，textinput=1，textoutput=2。 但实际情况却是textoutput=1，textinput无赋值。 所以想知道一下页面控件中，一个控件的ID与另一个控件的Name重复会有什么情况发生。希望能有大佬普及一下知识。

下面是函数中，通过函数计算得到gwp的值并判断绘图。 后面我想把这个计算得到的gwp的值直接在其他函数中调用，应该怎么改 比如gwp改成全局变量，麻烦指导下，有代码就更好 ``` $(function(){ var dom = document.getElementById("box4"); var myChart = echarts.init(dom); var app = {}; option = null; var y_f = []; //全局变量,wgid在gognweizongtu.js中获取 var gwp = 0; var xishu = [0.4,0.2,0.3,0.1]; var pjx = ["gzp","gyp","wlp","ryp"]; var pj = {"gongzhuang":"OK", "gongyi": "OK", "wuliao": "OK", "renyuan": "OK"}; var guige = [90, 90, 80, 75,85]; var xiang = ["gongzhuang","gongyi","wuliao","renyuan"]; for (var i = 0 ; i< xiang.length ; i++) { var lent = data[xiang[i]].y.length ; var ind = lent - 1 ; y_f.push(data[xiang[i]].y[ind]); if (data[xiang[i]].y[ind] < guige[i]){ pj[xiang[i]] = "NOK"; } document.getElementById(pjx[i]).innerHTML = pj[xiang[i]]; gwp += y_f[i]*xishu[i]; } y_f.push(88); if (gwp > 85.5){ document.getElementById("gwpj").innerHTML ="OK"; } gwp = gwp.toFixed(2); document.getElementById("gwp").innerHTML =gwp; document.getElementById("jinri").innerHTML =gwp; document.getElementById("zuori").innerHTML =gwp; document.getElementById("benzhou").innerHTML =gwp; document.getElementById("lishi").innerHTML =gwp; document.getElementById("gwp1").innerHTML =gwp1; /*绘图代码省略*/ }; if (option && typeof option === "object") { myChart.setOption(option, true); } }) ```

我实现了一个上传图片的功能，现在需要获取该图片的base64码赋值给一个对象。 ``` let fileDom = document.getElementById("inputLogo"); let previewDom = document.getElementById("preview"); fileDom.addEventListener("change", e => { let file = fileDom.files[0]; if (!file || file.type.indexOf("image/") < 0) { fileDom.value = ""; previewDom.src = ""; return; } let fileReader = new FileReader(); fileReader.onload = e => { previewDom.src = e.target.result; path = fileReader.result; }; fileReader.readAsDataURL(file); ``` 这里面我通过previewDom.src = e.target.result;获得的src是这样的,可以通过alert打印出来  但通过控制台输出previewDom.src,显示的是  通过path = fileReader.result;我在控制台可以得到base64码  但是alert打印没有效果. 请问一下:这是什么原因? target.result和result得到的值有什么区别? 我的目的是想要的到path这个变量的base64码,赋给一个对象 ``` obj = { header: { //在这里得到img的base64码,赋值给imgLogo imgLogo: path } } ``` 在控制台打印obj.header.imgLogo显示  这应该是没有赋值成功吧? 我想请教一下应该怎么做才能实现把我上传图片的base64码赋值给obj.header.imgLogo里面?

使用ajax查询数据，赋值给隐藏的页面，然后调用print()进行打印 不能用插件 ``` var i = 0; function printmore() { var orderRow = $('#dg').datagrid("getSelections"); var len = orderRow.length; if(i == len) { return; } $.ajax({ url : "${pageContext.request.contextPath}/printController/printtransmore?id=" + orderRow[i].id, type : "post", success : function(data) { $("#transNo").html("运单号：" + data.first.transportNo); $("#fromcompany").html( data.first.fromcompanyname + "<br/><br/>" + data.first.fromprovince + data.first.fromcity + data.first.fromarea + data.first.fromcompanyaddress); $("#tocompany").html( data.first.tocompanyname + "<br/><br/>" + data.first.toprovince + data.first.tocity + data.first.toarea + data.first.tocompanyaddress); $("#fromcontact").html( "联系人：" + data.first.fromcompanycontact + "&nbsp;&nbsp;电话：" + data.first.fromcompanyphoneno); $("#tocontact").html( "联系人：" + data.first.tocompanycontact + "&nbsp;&nbsp;电话：" + data.first.tocompanyphoneno); $("#pusername").html(data.trans.pagkageUserName); $("#money").html("运费："+data.trans.money); $("#insurance").html("其他费用：" + data.trans.insurance); $("#payname").html("付款方式：" + data.trans.payname); for (var a = 0; a < data.list.length; a++) { $("#boxno").html(data.list[a].boxNo); $("#typename").html(data.list[a].typeName); } $("#wcount").html("总重量：" + data.trans.weightCount); $("#bcount").html("总件数：" + data.trans.boxCount+"件"); printit('div1'); i = i + 1; printmore(); } }); } function printit(MyDiv) { //var newstr = document.all.item(myDiv).innerHTML; var newstr = document.getElementById(MyDiv).innerHTML; //alert(newstr); var oldstr = document.body.innerHTML; document.getElementById('printiframe').contentWindow.document.body.innerHTML = newstr; document.getElementById('printiframe').contentWindow.window.print(); document.getElementById('printiframe').contentWindow.document.body.innerHTML = oldstr; } ```

能帮忙指点下这代码应该怎么改，怎么没有结果啊，我就是想在函数中赋值，然后输出调用 ``` <!DOCTYPE html> <html> <body> <h2>JavaScript 函数</h2> <p>本例调用函数把华氏度转换为摄氏度：</p> <p id="gwp1"></p> <script> function () { var gwp=60； var gwp1=gwp+10; document.getElementById("gwp1").innerHTML =gwp1, }, </script> </body> </html> ```

0、这是需要定位的位置： ``` <input class="form-control listDate startDate" readonly="readonly" name="startDate" value="" type="text"> ``` 1、Python selenium，无法定位页面中的日期选择框，面向百度编程后发现可能是句柄的位置不对，于是加上了 ``` el_iframe=el_ywjg=browser.find_element_by_id('frame_content') browser.switch_to.frame('frame_content') ``` 2、仍然定位不到日期选择框，继续搜索后觉得可能是因为“readonly”属性，于是决定使用js去掉，但是这个框没有Id，于是换用getElementsByName（半路出家，完全不懂js，不知道对不对），于是变成了 ``` js="document.getElementsByName('startDate').removeAttribute('readonly')" browser.execute_script(js) ``` _报错：TypeError: document.getElementsByName(...).removeAttribute is not a function 3、查菜鸟教程发现“HTML DOM Document 对象方法”中，document.getElementById()返回的是一个对象，而我用的getElementsByName()返回的是一个对象集合，所以加上了一个[0]，变成： ``` js="document.getElementsByName('startDate')[0].removeAttribute('readonly')" browser.execute_script(js) ```__ _TypeError: document.getElementsByName(...)[0] is undefined 无计可施了，而且这个问题去搜索都搜不出来了……请各位前辈指教。_

要利用开源的PDF.js显示PDF，现在是通过直接改变搜索框的值 document.getElementById("findInput").value=txt; 我遇到的问题就是在改变搜索框里的值后，怎么加监听函数使得它立即响应搜索框值的变化，马上搜索新的值来来实现高亮显示

网上关于这方面的资料不多，普遍的方法为通过一个隐藏的表单传送JS的变量。哪位大佬能写个这个转换的代码~ ``` var UD = getUrlParam('userId'); document.form.UD2.value = UD; </style> <body> <form method="post" action="UserDetail.jsp" id ="passForm"> <input id = "UD2" type = "hidden" name="UD2"> </form> var formObj = document.getElementById('passForm'); formObj.submit(); <% request.setCharacterEncoding("utf-8"); String UD3 = request.getParameter("UD2");%> ``` 通过网上的方法，即将UD转成UD3，无论怎么跑UD3的值都是null，求助求助~

这是调showModalDialog的方法 window.showModalDialog("aa.jsp",{},"dialogHeight:400px;dialogWidth:320px;center:yes;resizable:no;scroll:no;status:no;"); 调用后在弹出页中定义onload方法去给一个文本框赋值，然后加载一棵树 window.onload = function() { document.getElementById("aa").value = "aaaa"; initTree(); } 经常会在第一次打开这个页面的时候不加载onload方法（文本框也没有赋值，树也没加载），但是如果不加载，再点一次就好了，剩下的基本上每次都没问题，请问有人知道是什么原因吗 先谢了
