我这里有以下脚本导致我出错:
var sections = ["#general_info", "#address_records", "#employment_history", "#driver_experience", "#military_experience", "#eeo_survey", "#psp_notice", "#eva"];
for(var i = 0; i < sections.length; i++){
$(sections[i]).find('input, select').each(function(){
$(this).change(function(){
validate();
$(this).closest('.placement').find('.module-heading').removeClass('module-heading-bad');
$(this).closest('.placement').find('.glyphicon').addClass('glyphicon-ok text-success');
$(this).closest('.placement').find('.glyphicon').removeClass('glyphicon-warning-sign text-danger');
$(sections[i]).find('input, select').each(function(){
if($(this).closest('div').hasClass('has-error')){
$(this).closest('.placement').find('.module-heading').addClass('module-heading-bad');
$(this).closest('.placement').find('.glyphicon').addClass('glyphicon-warning-sign text-danger');
$(this).closest('.placement').find('.glyphicon').removeClass('glyphicon-ok text-success');
return false;
}
});
});
});
}
function validate(){
var driving_qs = ['driving_exp_qa', 'driving_exp_qb', 'driving_exp_qc', 'driving_exp_qd'];
for( var i = 0; i < driving_qs.length; i++){
if($('input[name='+driving_qs[i]+']:checked').val()){
$('input[name='+driving_qs[i]+']').closest('.form-group').removeClass('has-error');
$('input[name='+driving_qs[i]+']').closest('.form-group').addClass('has-success');
}else{
$('input[name='+driving_qs[i]+']').closest('.form-group').addClass('has-error');
$('input[name='+driving_qs[i]+']').closest('.form-group').removeClass('has-success');
}
}
var fields = [{
selector: $('.not-empty'),
validations: [ isNotEmpty]
},{
selector: $('.email'),
validations: [ isNotEmpty, isEmail]
},{
selector: $('.number'),
validations: [ isNotEmpty, isNumber]
},{
selector: $('.number-noreq'),
validations: [isNumberNotRequired]
}];
$('.form-control').closest('div').removeClass('has-error');
var i = 0, k = 0, z = 0, j = fields.length, item, selector, fn, info;
for(; i < j; i++){
item = fields[i];
for(k = 0; k < item.validations.length; k++){
fn = item.validations[k];
for( z = 0; z < item.selector.length; z++){
selector = $(item.selector[z]);
info = selector.closest('div');
if(info)
var result = fn(selector.val());
if(result){
info.removeClass("has-error");
info.addClass('has-success');
}else{
info.removeClass('has-success');
info.addClass("has-error")
}
}
}
}
}
如果我在没有前面的for循环的情况下运行脚本,那么脚本运行得非常好。以下是我的代码所做的一步一步(注意:这没有for循环):
这个脚本将一直工作到每个部分的结尾,就像它应该做的那样。但是,在我尝试使用for loop
执行此操作后,它仅在一次输入后创建了成功方案。为什么会发生这种情况,甚至可能在我正在进行的循环中使用此函数?
下面我还包括了html标记的样本
<!-- this tag serves no purpose other than being a bookmark for scripting -->
<span class='placement'>
<!-- Section 1: General Information -->
<div id='general-heading' class='row module-heading module-heading-bad general' data-toggle='#general_info'>
<div class='form-group'>
<div class='col-md-12'>
<h4 class='text-info '>General Information<div id='general-confirmation' class='glyphicon glyphicon-warning-sign pull-right text-danger'></div></h4>
</div>
</div>
</div>
<div id='general_info' class='app-section'>
<div class='form-group'>
<div class='col-xs-12'>
<div class='form-group row'>
<div class='col-sm-6 col-xs-12'>
<label class='control-label'>First Name<span class='req'> *</span></label><br />
<input type='text' class='form-control not-empty' id='first_name' value="<?=$first_name?>"/>
</div>
<div class='col-sm-6 col-xs-12'>
<label class='control-label'>Middle Name</label><br />
<input type='text' class='form-control' id='middle_name' value="<?=$middle_name?>"/>
</div>
</div>
</div>
</div>
</span>

答案 0 :(得分:1)
此代码块中的问题:
for(var i = 0; i < sections.length; i++){
$(sections[i]).find('input, select').each(function(){
$(this).change(function(){
...
$(sections[i]).find('input, select').each(function(){
...
}
});
});
});
}
它是否使用变量i
,当function()
运行change
时,变量会发生变化。
在您的情况下,最简单的方法是使用forEach
函数而不是for循环,而不是使用索引:
sections.forEach(function(section){
$(section).find('input, select').each(function(){
$(this).change(function(){
...
$(section).find('input, select').each(function(){
...
}
});
});
});
})
这样可以确保您的i
每次都不同。
