流程形式变量 [英] process form var

问题描述

请仔细阅读此代码。我根本不是JS程序员，但是我不知道为什么在基本相同的上下文中为什么相同的行

在一个地方工作但是在另外，它会导致整个界面消失。


这是一个标签式界面，我只是想传递
$ f $ b在JS fxns中的options_total值。我没有得到错误输出

Javascript控制台...只是一个没有标签，面板或

表格的空白屏幕。


工作代码：用行调用


updateOptionsTotal（{$ optionset_id}，{$ productoption _id}，this.form）

函数updateOptionsTotal（set_id ，new_option_id，form）{

former_option_id = selected_options [set_id];

selected_options [set_id] = new_option_id;


options_total = eval（form.options_total.value）;


....


打破:(用线路调用：

writeTabPanel（this.form）;

函数writeTabPanel（form）{

var tpText ='''';

tpText + =''< div id ="'';

tpText + = this.tab.id;

tpText + =''" class =" tab" ; style =" top：'';

tpText + = this.tab.top;

tpText + =''; left：'';

tpText + = this.tab.left;

tpText + =' ;宽度：;

tpText + = this.tab.width;

tpText + =" onClick =" showPanel（\'''';

tpText + = this.tab.id +''\''，\''''+ this.panel.id;

options_total = eval（form.options_total.value）;

....

如果我注释掉最后一行，一切都很好 - 除了

之外，该值显然没有通过。

解决方案

Please give this code a look. I''m not a JS programmer at all, but I
can''t figure out why identical lines in essentially the same context
work in one place but in the other, it causes the entire interface to
disappear.

This is for a tabbed interface, and I''m just trying to pass the
options_total value around among the JS fxns. I get no error output in
the Javascript Console ... just a blank screen without tabs, panels, or
forms.

Working code: called with the line

updateOptionsTotal({$optionset_id},{$productoption _id},this.form)
function updateOptionsTotal(set_id,new_option_id,form) {
former_option_id = selected_options[set_id];
selected_options[set_id] = new_option_id;

options_total=eval(form.options_total.value);

....

Breaking: (called with the line:
writeTabPanel(this.form);
function writeTabPanel(form){
var tpText = '''';
tpText += ''<div id="'';
tpText += this.tab.id;
tpText += ''" class="tab" style="top:'';
tpText += this.tab.top;
tpText += '';left:'';
tpText += this.tab.left;
tpText += '';width:'';
tpText += this.tab.width;
tpText += ''" onClick="showPanel(\'''';
tpText += this.tab.id + ''\'',\'''' + this.panel.id;
options_total = eval(form.options_total.value);
....
If I comment out this last line, everything works great -- except that
the value obviously isn''t passed.
