javascript:为什么赢得这样的标记,造成一页的一切形式的重新set?
原标题:javascript: why won t this cause all the forms on a page to reset?

a. 优秀的编外师:

i 知道它应当简单,但一刀切,只是想去做。 这是应当如何做的,与以下网址相同:https://stackoverflow.com/questions/2146348/javascript-html-how-to-iterate- through-all-the-forms-on-a-page>;该研究员是如何做的:,BUT。 什么是错的?

var numberOfForms = document.getElementsByTagName("form");
console.log("numberOfForms: " + numberOfForms);
for (var i=0; i<numberOfForms.length; i++)
{
  document.forms[i].reset;
}

shed some light, plz. then i can punch out and hit the hay.

最佳回答

引证。 你已经用所有超文本的OM表格组成一个阵列。 使用<代码>编号为OfForms[i].reset(<>,而不是试图使用document.forms[n]

var numberOfForms = document.getElementsByTagName("form"); 
console.log("numberOfForms: " + numberOfForms); 
for (var i=0; i<numberOfForms.length; i++) 
{ 
   numberOfForms[i].reset();
} 

实际上,这是更清洁和更有效率的,实际上没有必要用<代码>文件.getElementsByTagName()将OMD带。

var allForms = document.forms;
for (var i=0; i < allForms.length; i++) {
  allForms[i].reset();
}
问题回答

使用<代码>reset()

var numberOfForms = document.getElementsByTagName("form");
console.log("numberOfForms: " + numberOfForms);
for (var i=0; i<numberOfForms.length; i++)
{
  document.forms[i].reset();
}
