使用JavaScript替换某些文本部分 [英] Replacing Certain Text Parts Using JavaScript

问题描述

我使用JavaScript将以下网址分配给网页中的变量。代码片段如下。

 googleURL = '  https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=' + '  GA％3Asource&安培;度量= GA％3Ausers&安培;排序= -ga％3Ausers&安培;开始日期= 2014年4月5日&安培;结束日期= 2014年4月23日&安培;最大结果= 10 '; 

startdate& enddate值是静态的。现在我希望那些相关的日期是动态的&日期将来自HTML表格&我已经完成了。这些值已经分配到2个不同的JS变量中。但我将这些变量添加到URL如下。

 googleURL = '  https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions='  + '  ga％3Asource& metrics = ga％3Ausers& sort = -ga％3Ausers& start-date = strStartDate& end-date = strEndDate& max-结果= 10'; 

请查看开始日期和结束日期，在那里你可以找到JS变量我用静态日期替换的名称。



当我改变编辑后的googleURL时，它显示如下。



https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers& ; start-date = strStartDate& end-date = strEndDate& max-results = 10



我认为变量值不分配t o或替换指定的变量。我正在使用的代码片段如下所示。

  var  strStartDate; 
  var  strEndDate; 
  var  googleURL; 
 
  //  以下JS函数会将表格中的值传递给URL。 / span> 
  function  passVariable（）{
 
 strStartDate =  document  .getElementById（  from_date）。value; 
 strEndDate =  document  .getElementById（  to_date 。）值; 
 
 alert（strStartDate）; 
 alert（strEndDate）; 
  //   alert（googleURL）;  
 文档 .WRITE（googleURL）; 
 
} 
 
 googleURL = '  https：// www。 googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions='<+'  GA％3Asource&安培;度量= GA％3Ausers&安培;排序= -ga％3Ausers&安培;开始日期= strStartDate&安培;结束日期= strEndDate&安培;最大结果= 10' ; 
 
 passVariable（）; 
 

我正在使用JavaScript。有人可以帮忙解决这个问题吗？

解决方案

你可以这样做



< pre lang =cs> var strStartDate;
var strEndDate;
var googleURL;

// 以下JS函数会将表格中的值传递给URL。 / span>
函数passVariable（）{

strStartDate = document.getElementById（ from_date）。 value ;
strEndDate = document.getElementById（ to_date）。值;

alert（strStartDate）;
alert（strEndDate）;

googleURL = ' https://www.googleapis.com/analytics/v3/data / ga？ids = ga％3A76546294& dimensions =' + ' ga％3Asource& metrics = ga％ 3个用户& sort = -ga％3Ausers& start-date =' + strStartDate + ' & end- date =' + strEndDate + ' & max-results = 10';

document.write（googleURL）;

}
passVariable（）;

I have the following URL assigned to a variable in a webpage using JavaScript. The code snippet is below.

googleURL = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions='+'ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-date=2014-04-05&end-date=2014-04-23&max-results=10';

The startdate & enddate values are static. Now I want that perticualr dates to be dynamic & the dates will be get from a HTML form & I already have that done. Those values are assigned into 2 different JS variables already. But I add those variables to the URL as below.

googleURL = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions='+'ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-date=strStartDate&end-date=strEndDate&max-results=10';

Please look at start-date and end-date, there you can find the JS variable names that I have replaced with static dates.

When I alterted the edited googleURL, it displays as at the below.

https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-date=strStartDate&end-date=strEndDate&max-results=10

I think the variable values are not assigning to or replacing the specified variables. The code snippet I'm working is at the below.

var strStartDate;
var strEndDate;
var googleURL;

//The following JS function will pass the values from the form to the URL.
function passVariable() {

  strStartDate = document.getElementById("from_date").value;
  strEndDate = document.getElementById("to_date").value;

  alert(strStartDate);
  alert(strEndDate);
  //alert(googleURL);
  document.write(googleURL);

}

 googleURL = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions='+'ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-date=strStartDate&end-date=strEndDate&max-results=10';

 passVariable();

I'm using JavaScript. could someone helpme to solve this matter?

Thanks & regards,

解决方案

you can done like this

var strStartDate;
var strEndDate;
var googleURL;

//The following JS function will pass the values from the form to the URL.
function passVariable() {

  strStartDate = document.getElementById("from_date").value;
  strEndDate = document.getElementById("to_date").value;

  alert(strStartDate);
  alert(strEndDate);

googleURL = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions='+'ga%3Asource&metrics=ga%3Ausers&sort=-ga%3Ausers&start-date=' + strStartDate + '&end-date=' + strEndDate + '&max-results=10';

  document.write(googleURL);

}
 passVariable();
