For循环在循环后删除正确的值

Question

我需要帮助理解为什么我的for循环会在数组中找到正确的行号，但一旦它离开循环，它将输出不正确的值。

Code.gs

//Determines the row the Field Office is in 
 
    for (var r = 0; r < dataValues.length; r++) { 
 
    if (dataValues[r][1] == theFormObject.fieldOfficeFFO) { 
 
     var q = dataValues[r][1]; 
 
     Logger.log('q inside loop: ' + q); //Row Value inside loop 
 
     Logger.log('r inside loop: ' + r); // Row number inside loop 
 
    } 
 
    } 
 
    Logger.log('q outside loop: ' + q); //Row Value outside loop 
 
    Logger.log('r outside loop: ' + r); // Row number outside loop

Logger.logs

你是对的罗宾，我是在Java的太多了。当然你需要休息一下。否则，循环继续，直到dataValues的长度达到，所以r是rizing。 中断告诉循环直接离开它，而不需要进一步处理。

//Determines the row the Field Office is in 
for (var r = 0; r < dataValues.length; r++) { 
    if (dataValues[r][1] == theFormObject.fieldOfficeFFO) { 
     var q = dataValues[r][1]; 
     Logger.log('q inside loop: ' + q); //Row Value inside loop 
     Logger.log('r inside loop: ' + r); // Row number inside loop 
     break; 
    } 
} 
Logger.log('q outside loop: ' + q); //Row Value outside loop 
Logger.log('r outside loop: ' + r); // Row number outside loop
