问题: 我有一个动态表单,使用JQuery步骤使其成为一个向导。现在,有一个步骤,下拉框选择触发AJAX调用,然后将表单字段添加到窗体。我需要这个字段所在的div的高度根据添加的字段数量变得更长。
IMAGES: 表格从两个下拉菜单开始: 一旦为第二个下拉列表选择了某些内容,就会进行AJAX调用并且表单附加字段。
灰色框应调整大小以容纳附加字段。
CODE: div的CSS如下:
.wizard > .content
{
background: #eee;
display: table-cell;
margin: 0.5em;
min-height: 35em;
position: relative;
width: auto;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
}
我可以在这里添加一个永久高度,但它不是动态的。
表单是Zend表单,因此HTML如下:
<div class="container-fluid">
<?php if ($this->error) : ?>
<div class="row-fluid">
<?php echo $this->error; ?>
</div>
<?php else : ?>
<?php echo $this->form()->openTag($form); ?>
<h3>Details</h3>
<section>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_PROJECT_NAME, false, true); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_PROJECT_DUE_DTTM, !($this->uberAdmin)); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_PROJECT_DESCRIPTION); ?>
</section>
<h3>Options</h3>
<section>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_REVIEW_PROJECT); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_WTL_PROJECT); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_JOB_TABLE); ?>
</section>
<h3>Project Configuration</h3>
<section>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_PROJECT_TYPES, !($this->uberAdmin), true); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_PROJECT_SUBTYPES, !($this->uberAdmin)); ?>
<?php
echo $this->partial('project/project/dynamicFormElements.phtml', array('form' => $this->projectForm, 'div' => 'project-config-elts'));
?>
</section>
<h3>Workflow Configuration</h3>
<section>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_WORKFLOW_TYPES, !($this->uberAdmin)); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_WORKFLOW_SUBTYPES, !($this->uberAdmin), true); ?>
<?php echo FormElementFactory::create($this, ProjectForm::KEY_PROJECT_WORKFLOW_CONFIG, !($this->uberAdmin)); ?>
</section>
突出显示的div是有问题的div。
我的AJAX调用在这里完成:
// Handle AJAX dynamic form creation results
function updateProjectForm(resp) {
$('div#project-config-elts').html(resp.html);
}
// Handle ajax error
function projectFormError(req, status, err) {
var errorString = '<div class="row-fluid alert alert-error">' +
'Error retrieving project form.' +
'</div>';
$('div#project-config-elts').html(errorString);
}
// AJAX request to get dynamic Project config form
function requestProjConfigForm() {
var request = {project_type: $('select[name=project_types]').val(),
project_subtype: $('select[name=project_subtypes]').val()
};
var ajaxOptions = {
url: 'projectform',
type:'POST',
dataType: 'json',
success: updateProjectForm,
error: projectFormError,
data: request
};
// Initiate the request!
$.ajax(ajaxOptions);
}
$('select[name=project_types]').change(function(){
updateProjectSubtypes();
});
// Handle a change in the selection of the particular project
$('select[name=project_subtypes]').change(function(){
requestProjConfigForm();
});
$('select[name=workflow_types]').change(function(){
updateWorkflowSubtypes();
});
$.validator.addMethod("validJSON", function(val, el) {
try {
JSON.parse(val);
return true;
} catch(e) {
return false;
}
}, "*Not valid JSON");
form.validate({
errorPlacement: function(error, element) {
$( element )
.closest( "form" )
.find( "label[for='" + element.attr( "id" ) + "']" )
.append( error );
},
rules: {
project_config: { validJSON: true }
}
});
我想在这里我可以动态改变高度,但我不太清楚如何做到这一点。

看起来你遇到了一个已经在jQuery Steps插件github页面上讨论过的问题:https://github.com/rstaib/jquery-steps/issues/147
基本上,由于阶梯内容的主体绝对位于百分比高度,因此它的高度不再基于其中的内容。人们过去常常尝试解决的一些问题是:按waqashsn:
.content > .body{
/*position: absolute*/
float:left;
width:95%;
height:95%;
padding:2.5%
}
这是AneeshRS的另一种选择,它会导致溢出的内容滚动:
.wizard.clearfix > .content.clearfix{
min-height: 500px;
overflow-y: auto;
}
查看问题页面的链接,以便更好地解释其中任何一个问题。但请注意,任何涉及移除绝对定位的解决方案都可能导致转换不再起作用。
